Personal Dosimetry for the Nuclear Industry.

The personal dosimetry fulfills the important duty to protect the health of radiation-exposed persons. Therefore exposed persons must carry dosimeters on them to ensure, that the allowed doses will not exceed. The records of the dosimeters must be analyzed, controlled and reported.

Efficient Managing of Personal Dosimetry

gs-soft developed in behalf of several Swiss nuclear power plants Perdos, a product that provides electronic support and efficient management for all processes of personal dosimetry. The system is used currently in the nuclear crafts of Beznau and Leibstadt as well as in the national interim storage facility for radioactive waste ZWILAG in Würenlingen.

Perdos administrates data in connection with work in radioactive zones. The system regulates entry controls, manages dosimeter data and supports the administrative processes of the personal dosimetry. As Perdos receives the current radiation doses continuously, it is able to warn the radiation protection officials immediately if necessary.

Along with the personal dosimetry, Perdos surveys as well the radioactive doses of activities in exposed zones. This enables the operators to optimize work flows by defining and distributing activities after acceptable radiation dosages.


The Swiss Federal Nuclear Safety Inspectorate ENSI closely cooperates with the individual nuclear plants. In order to protect staff, public and the environment, ENSI monitors compliance with radiological protection requirements and dose limits. The needed data and statistics are provided by Perdos.
