Radiation protection instrumentation - Passive integrating dosimetry systems for personal and environmental monitoring of photon and beta radiation
Radiation protection instrumentation - Passive integrating dosimetry systems for personal and environmental monitoring of photon and beta radiation
IEC 62387:2012 applies to all kinds of passive dosimetry systems that are used for measuring the personal dose equivalent (for whole body dosimetry), the personal dose equivalent (for eye lens dosimetry), the personal dose equivalent (for both whole body and extremity dosimetry), the ambient dose equivalent (for environmental dosimetry), or the directional dose equivalent (for environmental dosimetry). This standard applies to dosimetry systems that measure external photon and/or beta radiation in the dose range between 0,01 mSv and 10 Sv and in wide energy ranges. The dosimetry systems usually use electronic devices for the data evaluation and thus are often computer controlled.

Instrumentation pour la radioprotection - Systèmes dosimétriques intégrés passifs pour la surveillance de l’individu et de l'environnement des rayonnements photoniques et bêta
La CEI 62387:2012 s'applique à toutes sortes de systèmes dosimétriques passifs utilisés pour la mesure des équivalents de dose individuels (pour la dosimétrie du corps entier), des équivalents de dose individuels (pour la dosimétrie des cristallins), des équivalents de dose individuels (pour la dosimétrie du corps entier et pour la dosimétrie d'extrémités), de l'équivalent de dose ambiant (pour la dosimétrie de l'environnement), ou de l'équivalent de dose directionnel (pour la dosimétrie de l'environnement). La présente Norme s'applique aux systèmes dosimétriques qui mesurent les rayonnements photoniques et/ou bêta externes dans le domaine de dose allant de 0,01 mSv à 10 Sv et dans de vastes domaines d'énergie. Les systèmes dosimétriques utilisent habituellement des dispositifs électroniques pour l'évaluation des données et sont donc souvent commandés par ordinateur.
Instrumenti za zaščito pred sevanjem - Pasivni integrirni dozimetrijski sistemi za okoljsko in osebno nadzorovanje - 1. del: Splošne značilnosti in tehnične zahteve
IEC 62387:2012 se uporablja za vse vrste pasivnih dozimetrijskih sistemov za merjenje osebnih ekvivalentnih odmerkov (za dozimetrijo celega telesa), osebnih ekvivalentnih odmerkov (za dozimetrijo očesne leče), osebnih ekvivalentnih odmerkov (za dozimetrijo celotnega telesa in okončin), okoljskih ekvivalentnih odmerkov (za okoljsko dozimetrijo) ali usmerjenih ekvivalentnih odmerkov (za okoljsko dozimetrijo). Ta standard se uporablja za dozimetrijske sisteme, ki merijo zunanje fotonsko in/ali beta sevanje v razponu odmerkov med 0,01 mSv in 10 Sv ter v širših energetskih razponih. Dozimetrijski sistemi so običajno elektronski elementi za vrednotenje podatkov in so tako pogosto računalniško nadzorovani.

sufficient shielding which may cause a large over response from the side.
NOTE 2 If a = 60°, this means an irradiation from 60° to 120°.

shall not lose more than one indicated value, see 10.5.
For all influence quantities, the mandatory ranges are taken from IEC 61000-6-2.
The tests in lines 4, 5, and 7 of Table 14 need not to be done for readers for which the
manufacturer declares that either the respective influence quantity does not affect the
indicated value by more than 0,7·H during readout of dosemeters or the effect is
low
recognized and accompanied by an error message (at most one, see above) or the effect is
corrected for (for example by means of software). This declaration shall contain the necessary
evidence. This evidence can be a physical reason why the device is not affected by the
electromagnetic disturbance or why the electromagnetic disturbance is not present. This
evidence has to be stated for each electromagnetic disturbance separately. One example is,
that no mobile phones are allowed in the room of the reader.
36 Modification to 14.3
Replace the subclause by:
As the tests described in this clause are performed using rather low doses such as 7·H the
low
consideration of the natural background radiation is of special importance, see 5.2.4.
For the test according to lines 1 to 6 of Table 14 seven groups of n (≥ 10) dosemeters and for
the test according to line 7 of Table 14 one group of n (≥ 13) dosemeters shall be exposed to

a reference source with a dose equivalent of 7·H . For those influence quantities for which a
low
declaration of the manufacturer is available, see 14.2, no dosemeters need to be irradiated.
Group 1, reference group: no electromagnetic influences shall be present. To assure this,
appropriate filters, shieldings and so on shall be applied.
Groups 2, 6 and 8: in case the dosemeters contain any electric parts that may be sensitive to
electromagnetic disturbances (for example a DIS dosemeter), the dosemeters shall be
exposed to the influence quantities according to lines 1, 5 and 7 of Table 14 prior to their
readout. The radio frequency radiation shall be applied with the frequencies stated in footnote
d to Table 14.
Group 1 shall be read out without any electromagnetic influences.
Groups 2 to 8 shall be read out while the different electromagnetic influences are applied to
the reader in accordance with the standards of the IEC 61000-4 series as given in Table 14.
Each electromagnetic influence shall be applied for the duration of the readout of one
dosemeter. If possible, the output of the reader (for example glow curve) shall be observed.
Without error message, no abnormal chara
