38、g in nuclear power plants, laboratories and facilities handling radionuclides, and inhabitants living on territory which may be contaminated by either naturally occurring or artificial radionuclides. The purpose is to determine the dose equivalent to organs and the effective dose of internal radiati

39、on for the whole body. This standard is applicable both to equipment with spectroscopic capabilities and instruments for rapid screening for gross internal contamination only. This standard is applicable to instruments for the monitoring of certain critical organs (for example, lungs, thyroid gland,

40、 etc.) as well as instruments for monitoring the whole body. The standard applies to equipment for the measurement of the activity of gamma-emitting radionuclides in humans in order to determine the committed dose equivalent due to internal contamination in accordance with the recommendations of the

41、 ICRP 60 and ICRP 61. The requirements of the standard are applicable to the installed apparatus, to vehicle-mounted equipment and to portable instruments. However, Annex B defines the additional mechanical and environmental performance requirements and the additional testing required for transporta

42、ble and portable assemblies. The general and radiological requirements of all types of in vivo counters are included in this standard. Depending on the type of instrument and the organ to be checked, measurement geometry may require the subject of the monitoring procedure to stand, sit, or lie. The

43、detection assembly includes one or more radiation detector. Normally, these are shielded-scintillation or semi-conductor detectors. Where identification of the location of contamination is required, the detectors may be collimated. The measurement assembly includes functional units for the processin

44、g of signals from the detection assembly as well as units for the display of the measured activity. For the measurement of body mass a built-in weighing machine may be used. EN 61582:2006 8 The standard specifies general types, specific measuring characteristics, main test procedures, electrical and

45、 mechanical characteristics Text deleted, as well as the requirements related to background radiation of the environment. This equipment is not intended for the determination of external contamination of the human body or the clothing of personnel. This standard is not applicable to equipment such a

46、s radiation detectors intended for introduction into the human body. 2 Normative references The following referenced documents are indispensable for the application of this document.
