Population effective collective dose from nuclear medicine examination in Cuba

Abstract

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.

“…As shown in Table 3, there is quite a distinction between Admi nistrated Activities given by countries except in Brazil which has higher dos e in bone and thy roid scan compared with other countries. The resul ts of Administrated Activities in our studies in (Table 3) and ( Figure 5) regarding the average AA in (MBq) of different types of diagnostic examinations was compared wi th a surv ey from other countries (Vogiatzi, et al, 2011;Bomben et al, 2004;Khoury etal, 1994;Flores et al, 2006;Papadopoulos et al, 1990;Lai et al, 1995;M ettler et-al., 1986;DRL Japan, 2015). Table 4 and Figure 6 shows the range of radioisotope admi nistrated activities and the admi nistrated activity for Sudanese.…”

An update on radiation absorbed dose to patients from diagnostic nuclear medicine procedures in Tehran: A study on four academic centers

“…Comprehensive studies on diagnostic nuclear medicine procedures and their contribution to the population absorbed doses have been reported by many investigators worldwide. [ 10 11 12 13 14 15 16 17 18 ] However, despite the rapid growth of these procedures in Iran, there is a profound lack of statistics and the previous survey in Tehran was conducted a decade ago. [ 5 ] Compared to the previous study by the same group in the same centers,[ 19 ] striking differences are noted in trends of diagnostic nuclear medicine procedures.…”
