Assess whether the activities performed in the Nuclear Medicine service are significant in the total dose received by the workers and their relative contributions. Methods: measured independent variables: number of scintigraphies remaining in the examination room (N); eluted activity (E); Total activity marked in pharmaceuticals kits (K); number of times that was scheduled to work in the Hot room (Q); Variable dependent measured: cumulative effective dose in the period 10/2012 to 04/2013 added to each worker, obtained by information registered daily and monthly on activities and doses received in the period. Held Multiple Linear Regression (D = a + β_1 N + E + β_2 β_3 K + β_4 Q) with α = 0.05 significance level. It was concluded that the independent variables N (p = 0.097) and E (p = 0.086) did not significantly interfere with the Cumulative dose in the period. The K variables (p = 0.017) and Q (p = 0.028) were significant in the proposed model.
