Internal Dosimetry Exretion Analysis
Our internal dosimetry is accredited within the test center framework for the measurement of incorporated radionuclides using excretion analysis and for dose determination from these measurements.
Our methods include the direct measurement of beta emitters in urine (such as 3H, 14C, 32P, 33P and 125I) as well as beta measurement following chemical separation for the determination of 90Sr. Incorporation analysis of actinides (such as U, Th, Pu, Am and Cm) can be carried out from both urine and feces samples; due to the low detection limits required, chemical separation is performed in combination with alpha spectrometry. Our processes also allow several actinides to be determined simultaneously from one sample or 90Sr to be measured at the same time.
The dose is determined from the excreted activity measured, taking into account the corresponding excretion model for the identified radionuclide. This determination can be carried out in line with ICRP recommendations, directive 96/29/Euratom and the Austrian standard ÖNORM S5220.
Our measurement methods are constantly being advanced and are regularly checked by interlaboratory tests (PROCORAD, BfS). The processes are accredited within the test center framework. We would be pleased to send you our current price list on request.
