INTRODUCTION
Radiation protection instrumentation including those instruments used for the detection and

identification of radioactive material and radionuclides are used in many different

environments. They are typically exposed to different temperatures, humidity levels,

electromagnetic fields, and mechanical stresses such as shock and vibration during normal

use. Radiation instrumentation may be worn, hand carried, mounted to a vehicle, transported

from location to location, or installed. All of the conditions associated with these very different

uses should be considered when developing instrument-specific requirements. In order to

ensure consistency between standards, this environmental, electromagnetic, and mechanical

performance requirements standard was established.

5.3.2 Requirements for influence quantities

5.3.2.1 General
Unless stated otherwise the functional requirements established in an instrument-specific
standard shall be given in terms of change in functionality (e.g., alarm activation, loss of

display, etc.) or indicated reading (e.g., ±15 % of the average reading obtained in standard

conditions).
The instrument specific standard should indicate whether an influence quantity usually acts as

type S or F. The radiation level chosen for each test should be based on the type of influence

quantity as described in 5.3.2.2 and 5.3.2.3.

5.3.2.2 Tests for influence quantities of type S
These tests should be performed at an ambient dose equivalent (rate) that is low enough to
ensure that an effect from the test is measureable (e.g., 10 times the lower limit of the
effective range of measurement but not zero in order to be able to detect a reduction in the
indication).
5.3.2.3 Tests for influence quantities of type F
These tests may be performed at any ambient dose equivalent (rate). The ambient dose
equivalent (rate) chosen should be high enough to ensure that statistical fluctuations are
small enough to demonstrate whether the requirement is met (e.g., at least 10 times above
the lower limit of the measuring range).
5.3.3 Environmental requirements
Environmental requirements apply to different types of radiation systems based on their
design and expected use. The environmental requirements that apply to a specific instrument
are addressed by that instrument-specific standard. As a minimum ambient temperature and
relative humidity tests are required for all types of radiation detection systems. Other
environmental conditions shall be established as deemed appropriate by the project leader.
The following example text could be used in an individual standard as reference to this
standard: "The equipment shall undergo the tests specified in IEC 62706 "Environmental,
mechanical, and electromagnetic requirements for radiation protection instrumentation"
concerning the ambient temperature, relative humidity, and other metrological requirements
for [insert instrument designation here, i.e., body-worn, handheld, installed, etc.]
instrumentation.” It is advisable not to insert the year of publication in the normative
references citing IEC 62706. Thus, the latest edition of this standard will be considered.

5.3.4 Mechanical requirements
Mechanical requirements apply to different types of radiation systems based on their design
and expected use. The mechanical requirements that apply to a specific system are
addressed by that specific standard. As a minimum, vibration, mechanical shock, and impact
are required for all types of radiation detection systems.
The following example text could be used in an individual standard as reference to this
standard: "The equipment shall undergo the tests specified in IEC 62706 "Environmental,
mechanical, and electromagnetic requirements for radiation protection instrumentation"
concerning the mechanical requirements for [insert instrument designation here, i.e., body-
worn, handheld, installed, etc.] instrumentation.” It is advisable not to insert the year of
publication in the normative references citing IEC 62706. Thus, the latest edition of this
standard will be considered.

5.3.5 Electromagnetic requirements

Electromagnetic requirements apply to different types of radiation systems based on their

design and expected use. The electromagnetic requirements that apply to a specific system

are addressed by that specific standard. As a minimum, radio frequency immunity and

emissions are required for all types of radiation detection systems.

The following example text could be used in an individual standard as reference to this

standard: "The equipment shall undergo the tests specified in IEC 62706 "Environmental,
mechanical, and electromagnetic requirements for radiation protection instrumentation"

concerning the electromagnetic requirements for [insert instrument designation here, i.e.,

body-worn, handheld, installed, etc.] instrumentation.” It is advisable not to insert the year of

publication in the normative references citing IEC 62706. Thus, the latest edition of this
standard will be considered.
5.3.6 Functionality test
A functionality test verifying that the effects from an influence are within the instrument-
specific acceptance range shall be defined in the instrument-specific standard. These tests
are generally performed before, during and after the environmental conditions tests such as
temperature, humidity and electromagnetic, and before and after the mechanical
disturbances. Appropriate radiation sources specific to the type of instrument under test
should be used.
Functionality tests may include the following verifications:
• Instrument readings are within a specific range before and after exposure to an influence
quantity (e.g., post-test instrument readings are within ± x % of the pre-test value).
• No alarms, radionuclide identifications, increase or decrease in readings, or spurious
indications are observed during exposure to an influence quantity without the presence of
a radiation source.
• The instrument radionuclide identification capabilities are not degraded after exposure to
an influence quantity.
5.3.7 Additional requirements and test methods
Additional or alternative requirements and methods of test may be established in the specific
standard at the discretion of the project leader.
6 Radiation detection requirements
Radiation detection requirements are addressed in the instrument-specific standard.

7 Environmental requirements
7.1 General
Instruments may consist of multiple components that form a system, e.g., a dosimetry system
includes the reader and individual dosemeters. Individual components may be exposed to
different environments. Selection of environmental requirements shall consider the expected
conditions in which each component will be used. During testing, those components that will
not be exposed to an influence field (e.g., temperature) may be separated from the overall
system.
– 12 – 62706 © IEC:2012
7.2 Ambient temperature
7.2.1 Requirements
The manufacturer shall state the temperature range over which the instrument and all system
components will operate. Table 2 provides minimal temperature ranges for each instrument

type based on expected usage environments. Instruments may also consist of components to

form a system. In that system, individual components may be exposed to different

environments. Temperature requirements shall be established considering the expected

conditions in which each component will be used.

7.2.2 Method of test
Before starting each test the instrument under test shall be placed in an environmental
chamber set to a temperature of 20 °C ± 2 °C for at least 30 min or a time period that is
sufficiently long to ensure that the instrument has reached equilibrium with the temperature in
the test chamber. The relative humidity within the chamber should be less than 65 % to
prevent condensation during testing.
The test shall be performed once to the high temperature extreme and once to the low
temperature extreme. The temperature shall be linearly changed to the extreme temperature
–1
(high or low) at a rate not faster than 10 °C⋅h . The temperature of the test chamber shall be
maintained at the extreme temperature level for at least 4 h. The actual time period shall be
sufficiently long to ensure that the instrument has reached equilibrium with the environment.
Readings or functional changes occurring while the temperature is changing shall be
recorded. The readings (or other functions) of the instrument shall be recorded at the end of
the equilibrium time as defined in the instrument-specific standard.
Following either the high or low temperature exposure, the temperature in the test chamber
–1
shall be returned to 20 °C ± 2 °C at the controlled rate not exceeding 10 °C⋅h .
7.3 Temperature shock
7.3.1 Requirements
When appropriate, instruments shall be able to function within a manufacturer-stated period of
time following exposure to a rapid change in temperature from nominal (20 °C ± 2 °C) to the
high or low temperature value and back. The time required for an instrument to become
functional after each temperature change shall be stated by the manufacturer. The instrument
specific standard may state a maximum time if the manufacturer does not provide such
information.
NOTE It is expected that handheld or body-worn instrumentation will be exposed to temperature shock. Installed

and transportable equipment, including transportable equipment mounted on vehicle platforms, typically have
relatively large thermal masses resulting in a slow temperature change even when the ambient-temperature change
is rapid.
7.3.2 Method of test
Readings from the instrument under test shall be recorded while in a temperature of
20 °C ± 5 °C. The instrument under test shall then be exposed to the extreme temperature
(high or low) with the change taking place over a time interval of not more than 5 min. The
instrument should be kept in that temperature for a period of time until reaching thermal
equilibrium, e.g., 2 h. Readings should be obtained at specified time intervals, e.g., every
5 min. At the end of this part of the test, the instrument shall be placed in a temperature of
20 °C ± 5 °C with the change taking place over a time interval of not more than 5 min and held
at that temperature until reaching thermal equilibrium. Readings should be obtained using the
same technique as stated previously. Functionality tests shall be defined in the instrument-
specific standard.
62706 © IEC:2012 – 13 –
7.4 Relative humidity
7.4.1 Requirements
Instruments designed to operate in uncontrolled environments shall be able to function at
relative humidity levels of up to 93 % at temperatures up to 35 °C.

Based on the expected use and functional reliability requirements, some instruments may
require additional tests to verify case integrity. This can be achieved using a test where the

temperature is cycled while maintaining high relative humidity conditions (IEC 60068-2-38).

If an instrument will be used in a maritime environment, a salt fog/mist test should be

performed (IEC 60068-2-52).
7.4.2 Method of test
The instrument under test shall be placed in an environmental chamber at a temperature of
20 °C ± 2 °C and relative humidity of approximately 65 % and allowed to stabilize for a
minimum of 30 min. The temperature shall then be increased to 35 °C at a rate not exceeding
–1
10 °C⋅h . The relative humidity shall then be increased to 93 % ± 5 % at a rate of
approximately 10 % relative humidity per hour. The instrument under test should be observed
during the entire test in order to identify changes in function that could occur as a result of the
exposure to humidity. The relative humidity and temperature in the test chamber shall be
maintained for a minimum of 16 h. The relative humidity shall then be reduced to 40 % ± 3 %
at a rate of approximately 10 % relative humidity per hour while maintaining the temperature
at +35 °C ± 2 °C. After allowing a minimum of 2 h for equilibrium, the temperature and
humidity shall be returned to the nominal conditions at the change rates stated previously.
Functionality tests shall be defined in the instrument-specific standard.
7.5 Low/high temperature start-up
7.5.1 Requirements
When operated in non-weather protected environments, instruments shall be able to operate
when switched on at the cold or hot temperature limit.
7.5.2 Method of test
The instrument under test shall be placed in an environmental chamber at a temperature of
20 °C ± 2 °C. Switch on the instrument and verify functionality as required in the instrument-
specific standard when the instrument is ready for measurement. The instrument shall then be
switched off.
The temperature shall then be changed to the low temperature limit at a rate not exceeding
–1
10 °C⋅h . Allow the temperature to stabilize for a minimum of 2 h, or for a time period that is
sufficiently long to ensure all components reach thermal equilibrium. Switch on the
instrument and verify functionality as required in the instrument-specific standard when the
instrument is ready for measurement
Perform the same test starting from the nominal temperature going to the high temperature
limit.
7.6 IP (degree of protection) classification
7.6.1 Requirements
Enclosures or cases surrounding instruments or individual components of a system that may
be used in non-weather protected locations shall be designed to meet IP classifications as
defined in Table 2.
– 14 – 62706 © IEC:2012
7.6.2 Method of test
The method of test shall follow the IP requirements stated in IEC 60529. Those tests shall

include dust and moisture.
The instrument’s functionality shall be verified according to the instrument-specific standard.

8 Mechanical requirements
8.1 General
Instruments may consist of multiple components that form a system, e.g., a dosimetry system
includes the reader and individual dosemeters. A portal monitor may include a detection
assembly and a control assembly. Individual components may be exposed to different
environments. Selection of mechanical requirements shall consider the expected conditions in
which each component will be used. A summary of the requirements is shown in Table 3.
8.2 Drop
8.2.1 Requirements
Body worn instruments shall continue to function correctly after being dropped from a height
of 1 m onto a concrete surface on each of their six sides.
Handheld instruments shall continue to function correctly after being dropped from a height of
30 cm onto a hardwood surface on each side.
Instruments required to be transported in protective cases shall function correctly after being
dropped from a height of 1 m onto a concrete surface in their shipping case on each side.
There are no drop requirements for installed, mobile, and transportable equipment.
8.2.2 Method of test
A functionality test shall be performed before and after each drop test as required by the
instrument-specific standard. Drops shall be performed using methods to ensure only a single
side is exposed to the drop.
8.3 Vibration test
8.3.1 Handheld, body worn, portable, and transportable requirements

8.3.1.1 General
The instrument shall withstand exposure to random vibration environments using a spectral
2 -1
density of 0,01 g ⋅Hz with endpoints of 5 Hz and 500 Hz. The physical condition and
functionality of the instrument shall not be affected by the vibration exposure (e.g., solder
joints shall hold, nuts and bolts shall not come loose).
8.3.1.2 Method of test
Conduct a visual inspection and verify that the instrument is functioning properly as required
by the instrument specific standard. Subject the instrument to a random vibration at
2 –1
0,01 g ⋅Hz (spectral density) using 5 Hz and 500 Hz for the frequency endpoints for a
period of 1 h in each of three orthogonal orientations. After each 1 h vibration interval,
perform a functionality test based on the instrument-specific standard.
After the test, inspect the instrument for mechanical damage and loose components.

8.3.2 Installed requirements
8.3.2.1 General
Monitors or components that may be exposed to vibration (e.g., from heavy equipment
movement, vehicles, etc.) shall function normally when exposed to vibrations of up to 0,5 g

n
over a frequency range from 10 Hz to 150 Hz. The physical condition of the component or

monitor should not be affected by exposure (e.g., solder joints shall hold, nuts and bolts shall

not come loose). The monitor shall function correctly as required by the instrument-specific

standard throughout the vibration exposure and after the test.

8.3.2.2 Method of test
The test shall consist of 10 two-minute logarithmic sweep cycles of 0,5 g over a frequency
n
range from 10 Hz to 150 Hz. The orientation used for testing shall be the same as that used
when mounted in the field. The requirement is met if no alarms or other spurious indications
occur, and there is no substantial change in response as specified by the instrument-specific
standard. After the test, inspect the monitor for mechanical damage and loose components.
8.3.3 Mobile (ground vehicle mounted) requirements
8.3.3.1 General
The monitor shall function correctly as required by the instrument-specific standard when
exposed to vibrations associated with equipment installed on a ground vehicle. The vibration
exposure is based on the 5M2 classification found in IEC 60721-3-5. The accelerated spectra
