title: Intake risk and dose evaluation methods for workers in radiochemistry labs of a medical cyclotron facility.
abstract: The aim of this paper is to evaluate the risks and doses for the internal contamination of the radiochemistry staff in a high workload medical cyclotron facility. The doses from internal contamination derive from the inhalation of radioactive gas leakage from the cells by personnel involved in the synthesis processes and are calculated from urine sample measurements. Various models are considered for the calculation of the effective committed dose from the analysis of these urine samples, and the results are compared with data obtained from local environmental measurement of the radioactivity released inside the lab.
