Seven years of individual monitoring service in Cuba

The Center for Radiation Protection and Hygiene (CPHR) has been carrying out from 1987 the individual monitoring of workers occupationally exposed to the ionizing radiations in the Republic of Cuba, excepting those that employ X rays in diagnostic radiology. In this paper the results of the individual monitoring services during the period 1987-1993 are discussed. For all occupational practices the current system of dose limitation established in the country with 50 mSv as limit of annual dose is satisfied The distribution in all occupational practices other than Nuclear Medicine and Gammatherapy is characterized by having more than 95% of the controlled personnel with an effective dose lower than 5 mSv. In the case of Nuclear Medicine and Gammatherapy, more than 80% of the workers were below that dose value. For the practices evaluated in this paper the possibility of assuming the system of dose limitation recommended by ICRP is evident The evaluations carried out for the introduction of operational quantities Hp(0.07) and Hp(10) in dose assessment procedure are presented. The expressions obtained during the characterization of the film badge dosimeter, in terms of operational quantities guarantees a deviation of response of the dosimeter with depending upon energies, lower than 20%.
