THE REQUIREMENTS FOR PERSONAL MONITORING OF OCCUPATIONAL EXPOSURE: INTERNATIONAL EXPERIENCE AND UKRAINIAN REALITIES. / VYMOGY DO INDYVIDUAL'NOGO DOZYMETRYChNOGO KONTROLIu PROFESIINOGO OPROMINENNIa: SVITOVYI DOSVID TA UKRAÏNS'KI REALIÏ.

The article includes analysis and generalizations about international and national experience as well as regulatory requirements for the organization and performance of occupational monitoring for radiation exposure (category A personnel), filling of the national dose registries. It is shown that for practical reasons it is justifiable to provide universal individual monitoring of category A personnel, regardless of the expected dose of radiation. The establish ment and functioning the national dose registry should not be limited to the mechanical collection and accumulation of data of non-guaranteed quality. Instead, both a quality management program and a scientific and methodological center should become components of the dose monitoring and registration system ensuring the quality and reliability of data on occupational exposure doses. Besides the dose records, the data sets should include information about methods used, work conditions, employees' health status. Information exchange infrastructure and data protection policies should be built in accordance with national approaches under the auspices of the State Agency for E-Governance in Ukraine.

Methodological approach to developing of double dosimetry algorithms and its application in the interventional cardiology.

STUDY OBJECTIVES: to develop taking into account the specifity of exposure conditions a new algorithm for interventional cardiologists who use the X-ray protective clothes. MATERIALS AND METHODS: modelling of the typical conditions of radiation exposure of interventional cardiologist wearing protective clothes during the interventions, providing Monte-Carlo computations of organ doses and dosimeters readouts. RESULTS: partial dose values for all possible radiation conditions and relative frequency weight coefficients for each condition were obtained by Monte-Carlo method. CONCLUSIONS: flexible and adaptive methodology for algorithm developing was proposed, a more specific algorithm was obtained for typical radiation conditions occuring under the interventional cardiology procedures. This algorithm well corresponded to experimental measurements demonstrating at that less conservatism comparing to other known algorithms.
