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.

The specific activity of Ra-226 in drinking water ranged from 15 ± 5 mBq.lˉ¹ to 39 ± 12 mBq.lˉ¹. The mean specific activity of Ra-226 was fount to be 27 ± 8 mBq.lˉ¹. No seasonal variation was found. Water samples were collected from the two main sources of drinking water: private wells and governmental water supply system, being the mean specific activities of Ra-226: 25 ± 7 mBq.lˉ¹ and 31 ± 9 mBq.lˉ¹, respectively. Based upon measured concentrations the age-dependent associated effective dose due to the ingestion of Ra-226, as a consequence of direct consumption of drinking water, has been calculated. For the age interval 1 year to 5 years, the average effective dose was 6.2 Sv.yˉ¹, and for adults the average effective dose was 5.2 Sv.yˉ¹.

The average annual frequency of examinations was estimated to be 3.82 per 1000 population. The results show that nuclear medicine techniques of thyroid explorations with 43.73% and iodide 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 21073 nuclear medicine procedures.
