SUPPORT SYSTEM FOR THE DOSIMETRIC INTERPRETATION OF THE INTERNAL EXPOSURE

Paper describes the computer system, which was developed for the purposes of the retrospective dosimetry of internal exposure by specialists of the Radiation Protection Institute of Academy of Technological Sciences of Ukraine. The system gives tools for analysis and interpretation of biophysical measurements, for reconstruction of intakes and related doses of the internal exposure. The main aim of the system is retrospective estimation of the doses of internal exposure from single acute or multiple intakes of radionuclides on the base of the bioassay and whole body counter measurements

ENSURING OF RADIATION PROTECTION DURING WORKS ON TRANSFORMATION OF THE OBJECT SHELTER INTO ECOLOGICALLY SAFE SYSTEM. BIOPHYSICAL MONITORING OF THE PERSONNEL INTERNAL EXPOSURE DOSES

Given paper, states the ensuring of the interpretation of the basic radiation protection principles, relative to the works at the Object Shelter (OS). Analysis of the factors of radiation situation at the OS is figured out. Functioning at the present time individual dose monitoring (IDM) system at the OS is describe. The system is based on the methods of biophysical monitoring. A series of the results, obtained during internal exposure individual dose monitoring of the personnel is presented. It is mentioned, that implementation of the internal exposure dose biophysical monitoring system (during the works on transformation of the OS into ecologically safe system) allows:  provide adequate level of the IDM of the internal exposure dose (the level is corresponds to the present day requirements of the radiation protection); develop the recommendations on selection of individual means of protection of respiratory tract; ensure determination of the parameters of radioactive air contamination in the work areas; and, provide the optimal planning of dose load to the personnel

Приведен анализ факторов радиационной обстановки на ОУ. Описана действующая в настоящий момент на ОУ система контроля индивидуальных доз (ИДК) внутреннего облучения персонала, основанная на методах биофизического контроля. Приведен ряд результатов, полученных по итогам выполнения контроля индивидуальных доз внутреннего облучения персонала. Отмечается, что внедрение системы биофизического контроля доз внутреннего облучения при выполнении работ по преобразованию ОУ в экологически безопасную систему позволило обеспечить адекватный, соответствующий современным требованиям радиационной защиты, уровень ИДК доз внутреннего облучения персонала, своевременно разработать рекомендации по выбору средств индивидуальной защиты органов дыхания, обеспечить определение параметров радиоактивного загрязнения воздуха в зонах производства работ и обеспечить оптимальное планирование дозовых нагрузок на персонал
