| Popis: | In the event of a radiation emergency, it is necessary to assess intake and radiation dose for the internally contaminated casualties. This paper provides relatively rapid and simple procedures of bioassay. Faeces samples were ashed to improve sample homogeneity. Gamma spectrometry was used for radioactivity measurement. The measured results, including activity of the biosamples and associated uncertainty, were evaluated for traceability based on ANSI N42.22 and bias and precision based on ANIS/HPS N13.30. For all urine customary exercise samples, measurement results of 60Co and 137Cs were in good agreement with NIST values within 5% and satisfied ANSI N42.22 and ANIS/HPS N13.30 acceptance criteria. In contrast, the uncertainty of 57Co was quite large and the activity differed from the NIST value by 18%. For the urine emergency preparedness exercise, all measured results agreed well with NIST values, with less than 10% difference. Synthetic faeces samples included 54Mn, 60Co, and 134Cs. The activi... |
