Radiation protection instrumentation - Passive integrating dosimetry systems for environmental and personal monitoring - Part 1: General characteristics and performance requirements

This part of IEC 62387 applies to all kinds of passive dosimetry systems that are used for measuring the personal dose equivalents Hp(10) or Hp(0,07) or the ambient dose equivalent H*(10). It applies to dosimetry systems that measure external photon or beta radiation in the dose range between 0,01 mSv and 10 Sv and in the energy ranges given in the following Table. All the energy values are mean energies with respect to the prevailing dose quantity. The dosimetry systems usually use electronic devices for the data evaluation and thus are often computer controlled.

Est destinée aux systèmes dosimétriques qui sont capables d'évaluer des doses dans la grandeur et l'unité exigées (Sv) à partir des signaux de lecture dans chaque grandeur et unité. La seule correction qui peut être appliquée à la dose évaluée (valeur indiquée) est celle qui résulte du bruit de fond dû au rayonnement naturel en utilisant des dosimètres supplémentaires.

Instrumenti za zaščito pred sevanjem - Pasivni integrirni dozimetrijski sistemi za okoljsko in osebno nadzorovanje - 1. del: Splošne značilnosti in tehnične zahteve

Ta del standarda IEC 62387 se uporablja za vse vrste pasivnih dozimetrijskih sistemov za merjenje osebnih ekvivalentnih odmerkov Hp(10) ali Hp(0,07) ali okoljskih ekvivalentnih odmerkov H*(10). Uporablja se za dozimetrijske sisteme, ki merijo zunanje fotonsko ali beta sevanje v razponu odmerkov med 0,01 mSv in 10 Sv ter v energetskih razponih iz naslednje tabele. Vse energetske vrednosti so povprečja glede na prevladujočo količino odmerka. Dozimetrijski sistemi so običajno elektronski elementi za vrednotenje podatkov in so tako pogosto računalniško nadzorovani.

dosemeters, readers, and additional equipment. In addition, the corresponding methods of test
to check that these requirements are met are given in detail,
• harmonize requirements for all types of passive dosimetry systems detecting external photon
and beta radiation,
• specify the use the operational quantities according to ICRU 51,
• harmonize tests using radiation with relevant ISO standards on reference radiation and
calibration: ISO 4037 for photon radiation, ISO 6980 for beta radiation and ISO 8529 for neutron
radiation. For this reason, no conversion coefficients from air kerma (or absorbed dose or
fluence) to the operational quantities are given in this standard, except in case the necessary
conversion coefficients are not included in the respective ISO standard. Those given in the ISO-
standards are applicable,
• incorporate basic terms of the concept that a result of a measurement essentially consists of a
value and an associated uncertainty, as laid down in the introductions of IEV 311 and EN 60359
and refer the reader to an IEC technical report for complete uncertainty analysis in radiation
protection measurements and to the GUM,
• align CENELEC performance requirements on dosimetry systems for measuring personal dose
equivalents with the recommendations on accuracy stated in the ICRP Publication 75: General
Principles for the Radiation Protection of Workers. Further information is given in the informative
Annex ZB.

Introduction



A dosimetry system may consist of the following elements:
a) a passive device, referred to here as a detector, which, after the presence of radiation, provides
and stores a signal for use in measuring one or more quantities of the incident radiation field;
b) a dosemeter, that incorporates some means of identification and contains one or more
detectors;
c) a reader which is used to readout the stored information (signal) from the detector, in order to
determine the radiation dose;
d) a computer with appropriate software to control the reader, store the signals transmitted from
the reader, calculate, display and store the evaluated dose in the form of an electronic file or
paper copy;
e) additional equipment and documented procedures (instruction manual) for performing
associated processes such as deleting stored dose information, cleaning dosemeters, or those
needed to ensure the effectiveness of the whole system.

SIST EN 62387-1:2012

1 Scope and object
This European Standard applies to all kinds of passive dosimetry systems that are used for
measuring
– the personal dose equivalent H (10) (for whole body dosimetry),
p
– the personal dose equivalent H (0,07) (for both whole body and extremity dosimetry),or
p
– the ambient dose equivalent H*(10) (for environmental dosimetry).
It applies to dosimetry systems that measure external photon or beta radiation in the dose range
between 0,01 mSv and 10 Sv and in the energy ranges given in the following Table. All the energy
values are mean energies with respect to the prevailing dose quantity. The dosimetry systems
usually use electronic devices for the data evaluation and thus are often computer controlled.

For beta-particle radiation, an energy of 0,07 MeV is required to penetrate the dead layer of skin of 0,07 mm
(almost equivalent to 0,07 mm of ICRU tissue).

NOTE 1  In this standard, “dose” means personal or ambient dose equivalent, unless otherwise stated.
NOTE 2  For H (10) and H*(10) no beta radiation is considered. Reasons: 1) H (10) and H*(10) are a conservative
p p
estimate for the effective dose which is not a suitable quantity for beta radiation. 2) No conversion coefficients are
available in ICRU 56, ICRU 57 or ISO 6980.
NOTE 3  The maximum energy ranges are the energy limits within which type tests according to this standard are
possible.
In addition, this standard can be applied for testing neutron dosimetry systems concerning the
design (Clause 8), the instruction manual (Clause 9), the software (Clause 10), environmental
influences (Clause 13), electromagnetic influences (Clause 14), mechanical influences (Clause 15),
and the documentation (Clause 16). The test utilizing radiation (Clauses 13 to 15) shall be done
with neutron reference radiation qualities according to the ISO 8529 series.
In some countries the presence of beta dose has to be indicated by dosemeters worn on the trunk.
Such an indication of the presence of beta dose is not a measurement. For that reason, a specific
subclause (11.8) deals with the indication of the presence of beta dose.
This standard is intended to be applied to dosimetry systems that are capable of evaluating doses
in the required quantity and unit (Sv) from readout signals in any quantity and unit. The only
correction that may be applied to the evaluated dose (indicated value) is the one resulting from
natural background radiation using extra dosemeters.
NOTE 4  The correction due to natural background may be made before or after the dose calculation.
Usually, a dosimetry system is not able to measure all quantities given above. Thus, the systems
shall only be tested with regards to those quantities and types of radiation it is intended to be used
for. Annex D gives further guidelines to define specific usage categories.
Full compliance with this standard is given if the requirements for the mandatory ranges given in
Tables 3 to 5 are fulfilled. If the customer or manufacturer requires extended ranges then the test
should also be performed as specified in this standard, i.e. the requirements given in Tables 3 to 5
apply, too. The range of any influence quantity stated by the manufacturer is called rated range.
Thus, dosimetry systems can be classified by stating a set of ranges (for example, for dose, for
energy, for temperature) within which the requirements stated in this standard are met (Capabilities
of the system, see Clause 7). In addition, usage categories are given in Annex D with respect to
different measuring capabilities.

For the dosimetry systems described above, this standard specifies general characteristics, general
test procedures and performance requirements, radiation characteristics as well as environmental,
electrical, mechanical, software and safety characteristics.
A dosimetry system may be tested with regards to different quantities at different times. In case the
dosimetry system was changed since the previous test, a new test with regards to quantities tests
formerly may be necessary.
The absolute calibration of the dosimetry system is not checked during a type test according to this
standard as only system properties are of interest. The absolute calibration is checked during a
routine test.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
For definitions related to measurements in general, definitions were taken from
IEC 60050-300, Part 311, from IEC 60050-393 and from IEC 60050-394. A very limited number of
definitions was taken from ISO 4037-3 and the ISO Guide to the Expression of Uncertainty in
Measurement (GUM).
The references are given in brackets [ ]. The information following the brackets is specific to this
standard and is not originating from the given source.
A word between parentheses ( ) in the title of a definition is a qualifier that may be skipped if there
is no danger of confusion with a similar term.
The terms are listed in alphabetical order.
3.1
ambient dose equivalent
H*(d)
at a point in a radiation field, dose equivalent that would be produced by the corresponding
expanded and aligned field, in the ICRU sphere at a depth, d, on the radius opposing the direction
of the aligned field
[SOURCE: ICRU 51]
Note 1 to entry: The recommended depth, d, for environmental monitoring in terms of H*(d) is 10 mm, and H*(d) may be
written as H*(10). [IEV 393-14-95]
3.2
calibration factor
N
0
quotient of the conventional true value of a quantity C and the indicated value G at the point of
r,0 r,0
test for a reference radiation under reference conditions. It is expressed as
C
r,0
N =
0
G
r,0
Note 1 to entry: The reciprocal of the calibration factor is equal to the response under reference conditions. In contrast to
the calibration factor, which refers to the reference conditions only, the response refers to any conditions prevailing at the
time of measurement.
[SOURCE: ISO 4037-3, Definition 3.2.12, modified]
Note 2 to entry: This definition is of special importance for non-linear dosemeters.
Note 3 to entry: The reference value C for the dose is given in Table 2.

[SOURCE: IEV 394-20-14, modified]
3.4
conventional true value (of a quantity)
C
value attributed to a particular quantity and accepted, sometimes by convention, as having an
uncertainty appropriate for a given purpose
Note 1 to entry: "Conventional true value" is sometimes called “assigned value”, “best estimate of the value”,
“conventional value” or “reference value”.
[SOURCE: GUM B.2.4]
3.5
correction for non-linearity
r
n
quotient of the response R under conditions where only the value of the dose equivalent is varied,
n
and the reference response R . It is expressed as
0

R
0
Note 1 to entry: For a linear dosimetry system, r is equal to unity.
n
3.6
coverage factor
k
numerical factor used as a multiplier of the combined standard uncertainty in order to obtain an
expanded uncertainty
Note 1 to entry: A coverage factor k is typically in the range 2 to 3.
[SOURCE: GUM 2.3.6]
Note 2 to entry: In case of a normal distribution, using a coverage factor of 2 results in an expanded uncertainty that
defines an interval around the result of a measurement that contains approximately 95 % of the distribution of values that
could reasonably be attributed to the measurand. For other distributions, the coverage factor may be larger.
3.7
detector
element of equipment or a substance which, in the presence of radiation, provides a signal for use
in measuring one or more quantities of the incident radiation

[SOURCE: IEV 394-04-01]
Note 1 to entry: The detector usually requires a separate reader to read out the signal. That means the detector usually is
not able to provide a signal without any external reading process.
Note 2 to entry: A passive detector does not need an external power supply to collect and store dose information.
Note 3 to entry: In IEV, the term reads “radiation detector”.

deviation
D
difference between the indicated values for the same value of the measurand of a dosimetry
system, when an influence quantity assumes, successively, two different values
[SOURCE: IEV 311-07-03, modified]
D = G – G
r
where
G the indicated value under the effect; and
G the indicated value under reference conditions.
r
Note 1 to entry: The original term in IEV 311-07-03 reads “variation (due to an influence quantity)”. In order not to mix up
variation (of the indicated value) and variation of the response, in this standard, the term is called “deviation”.
Note 2 to entry: The deviation can be positive or negative resulting in an increase or a decrease of the indicated value,
respectively.
