HIGH-DOSE STANDARDIZATION STUDY FOR g-RAYS RADIATION PROCESSING AT NIM

Y. Yang, Y. Zhang, J. Gao
Abstract:
The high dose standard and dissemination system of g-rays has already established at NIM. Fricke dosimetry is accepted as primary standard. The transfer standards include alanine/ESR dosimetry and dichromate solution dosimetry. Those dosimeters possess many favorable characteristics, such as good linearity, long shelflife, reproducible and stable radiation response and equivalence to water in terms of radiation absorption properties.
In order to guaranteeing the product quality of radiation processing and promoting the progress of radiation techniques. On April 18, 1990, SBTS and SCST had jointly issued “the Provisional Regulation of Metrological Supervision and Management for Radiation processing”. This regulation stipulates that all the enterprises and institutions dealing with radiation processing should apply for “the Measurement License for Radiation Processing” from the local metrological administrative department of provincial government.
