Abstract
In case of criticality accident, the characteristics of the radiation produced (photons and neutrons) must be determined in order to specify the risks to an exposed individual. The SNAC2 area dosemeter, an improvement of SNAC50, makes it possible to restore neutron spectrum shapes from the integral data of a few activation detectors, and to calculate the useful dosimetric quantities with the appropriate conversion factors. The thermal and epithermal components of the spectral distribution are determined by means of (1) bare copper and (2) cadmium shielded gold and copper. The fast component of the spectrum is obtained with three threshold detectors, viz indium, nickel and magnesium allowing to assess the parameters of a representative mathematical function. The spectrum indexes make it possible to find out the variations of the spectral di stribution in order to obtain the dosimetric quantities ranges. An ebonite disk (sulfur activation) is included for the assessment of the dosimetric quantities to an exposed individual. The measurements of the sample activity are carried out by gamma spectrometry, except for ebonite which requires beta activity counting. Data processing is carried out on a microcomputer. The BASIC programme is lis ted in appendix.
