What is PD IEC/TS 62743-Electronic counting dosemeters for pulsed fields of ionizing radiation about?
PD IEC/TS 62743 is a technical specification on radiation protection instrumentation that discusses the electronic counting dosemeters for pulsed fields of ionizing radiation to ensure protection against radiation hazards.
PD IEC/TS 62743 applies to all types of counting dosemeters, irrespective of the measuring quantity and the type of radiation intended to be measured.
PD IEC/TS 62743 ensures that a single radiation pulse can be correctly measured even if the dosemeter is in the internal state relevant for measuring background or environmental radiation.
The characteristics of the dosemeter for repeated pulses are expected to be better than for one single radiation pulse with the same parameters but worse than for continuous radiation, i.e., in between the characteristics for these two extreme conditions.
The pulsed radiation source is characterized by the parameters
- Radiation pulse duration, tpulse
- Pulse peak dose rate, Hpulse,peak
- Dose per radiation pulse, Hpulse
PD IEC/TS 62743 considers the pulsation of the radiation field as an additional influence quantity like particle energy and direction of radiation incidence. Therefore, the tests described are additional to all the tests in the respective standards.
PD IEC/TS 62743 describes methods to determine the characteristic parameters of the counting dosemeter. A prerequisite of the method is that the model function of the dosemeter can sufficiently be approximated by
Gdose = Gcount × ncount × kdead
where Gdose is the dose indication of the dosemeter,
Gcount is the dose indication per counting event,
ncount is the number of counting events counted by the dosemeter, and
kdead is the correction for dead time losses.
PD IEC/TS 62743 is applicable to all types of radiation for which a suitable pulsed reference field is available, and all other requirements are fulfilled.
Note: PD IEC/TS 62743 does not apply for those types of counting dosemeters that either
- Do not have an indication or software read-out of the dose rate and the number of pulses counted
- Convert the non-pulsed detector signal to counts by a converter, or
- Use nuclear reactions to generate long and continuous secondary radiation fields which then are measured by the dosemeter using counting techniques instead of measuring the direct radiation pulse
