Population effective collective dose from nuclear medicine examination in Cuba.
In an attempt to estimate the effective collective dose imparted to the population of Camagüey-Ciego de Avila territory, Cuba, we have made use of the statistics from nuclear medicine examinations given to a population of 1.1 million inhabitants for the years 1995-1999. The average annual frequency of examinations was estimated to be 3.82 per 1000 population. The results show that nuclear medicine techniques of thyroid imaging with 43.73% and thyroid uptake with 43.36% are the main techniques implicated in the relative contribution to the total annual effective collective dose, which averaged 54.43 man Sv for the studied period. Radiation risks for the Camagüey-Ciego de Avila population caused by nuclear medicine examinations in the period studied were calculated: the total number of fatal and non-fatal cancers was 16.33 and the number of serious hereditary disturbance was 3.54 as a result of 21,073 nuclear medicine procedures, corresponding to a total detriment of one case per thousand examinations.
