[en] This case concerns a wound contaminated by plutonium. In managing the consequences of such an incident, the occupational physician of a nuclear installation has to solve various questions in the field of dosimetry, communication and regulation. Dosimetry and risk evaluation of internal contamination are complex. Dose limits are annual limits and it is difficult to explain to the victim that for internal contamination the decision concerning the ability to work in controlled areas is determined on the basis of a committed dose on 50 years. Moreover, the notification of such an incident to the employer, to the labour inspectorate and to the governmental organism of control of radiation protection needs an important involvement in the domain of information. This case allows us to describe various practical aspects of medical management and dosimetry. The follow-up of measurements and therapy is given for a period of more than five years. (authors)
