Legal reference: §§ 126 - 132 Radiation Protection Act (StrlSchG) and §§ 155 - 158 Radiation Protection Ordinance (StrlSchV).

According to the StrlSchG, a workplace is defined as a place where a worker regularly or repeatedly stays during the course of his work. Whoever is responsible for a workplace in the ground floor or basement of a building in radon precautionary areas must carry out and complete measurements of the radon activity concentration within 18 months after the announcement of these areas (i.e. by 30.06.2022 at the latest). The prescribed measurement period is 12 months and shall be carried out by a body recognized according to §155 StrlSchV using suitable measuring instruments. The obligation to perform these radon measurements also extends to rooms in rented business premises. This essentially includes all office and recreation rooms on the ground floor and basement of buildings. In addition, there are rooms in which, for example, janitors, technicians, cleaning staff, canteen staff and other employees are located. Boiler rooms and server rooms do not count as workplaces according to StrlSchV.
According to Annex 8 of the Radiation Protection Act (StrlSchG), employers are obliged to estimate the radiation exposure of employees in the case of "work areas with increased exposure to radon". This must be carried out over a period of 12 months. This also applies to work areas outside of areas suspected of being affected by radon. To these fields of work belong:

  • working places in underground mines, shafts and caves, including visitor mines,
  • workstations in radon healing baths and radon healing tunnels,
  • workplaces in plants for water extraction, treatment and Distribution.


Important note on your order

Personal radon exposure is determined by means of a personal exposimeter and the necessary reference exposimeter (also ALTRAC type PD), which must be ordered separately.


Measurement procedure

  • The determination of personal radon exposure is carried out by means of a personal exposimeter and a reference exposimeter supplied with the device.
  • The procedure is as follows:
  • The personal exposure meter (with clip) is to be worn on work clothes (e.g. breast pocket work suit). The daily wearing times (= the time when it is not next to the reference exposimeter set up in the changing room) are noted in the table on the accompanying slip.
  • The reference exposimeter is to be set up in the room where the personal exposimeter is stored outside working hours, e.g. changing room, office, car or in open air conditions.
  • The measuring time is 3-6 months. The requirement of a minimum measuring time of 1 year is also fulfilled by several consecutive individual measurements.


After the measurement

  • Please return the exposimeters to the ALTRAC test laboratory as soon as possible after completion of the measurement.
  • If possible, the exposimeters should be sent back to the laboratory in their original packaging (which is radon-proof).
  • After analysis of the exposed detectors you will receive a detailed test report by letter.
