​The French national network for environmental radioactivity measurements centralizes all the monitoring data on environmental radioactivity in France and ensures their quality and harmonization through an accreditation procedure. Its website is now available in English.

Description
  
  

In dental field, imaging practices (retro alveolar, dental panoramic, teleradiography, scanning, etc.) require the dosimetric monitoring of persons performing these acts. Most often, this monitoring is done using a "chest" dosimeter changed every quarter. Some workplace studies show that a monthly "chest" dosimeter is required. Maintenance of the detector (film or digital) by the operator can generate doses to the fingers such that a monitoring of the ends with a ring dosimeter could be advised. The environmental dosimeter (s) is also recommended for measuring the ambient dose in working areas in accordance with the regulations and the standards in force.

Radiation exposure is generally low in conventional radiology but significantly higher in interventional radiology. Particular attention should also be paid in the operating room. In interventional radiology and in the operating room, in addition to the chest monitoring, additional dosimeters like rings or wrists must be used to monitor the extremity doses, as well as eye lens dosimeters to monitor the eye dose level if necessary. Environmental dosimeters can also be used to measure the ambient dose in working areas in accordance with regulations and standards in force. In radiotherapy, it may be appropriate to use individual and / or environmental dosimeters able to measure the neutron dose.

​Persons involved in animal imaging requires dosimetric monitoring . As an example, and subject to workplace study, a veterinarian practicing under good conditions 500 x rays a year must wear a "chest" dosimeter changed quarterly. It may also be necessary to carry out a dosimetric monitoring of extremities with ring or wrist dosimeters for whose who to have hold animals  near the primary beam. In all cases, environmental dosimeters will also be used to measure the environmental dose in working areas in accordance with the regulations and standards in force.

​In the nuclear field, ionizing radiation exposure is directly linked to workplaces. The Radiological Protection Services are in charge in studies of the work place to adapt individual and environmental dosimetric monitoring. This monitoring will be carried out with monthly or quarterly "chest" dosimeters adapted to the type of radiation: beta, X rays  gamma and possibly neutron. 'Glove box' work, for example, will require wearing a ring or wrist dosimeter. Environmental dosimeters will also be used to measure the environmental dose in working areas in accordance with the regulations and standards in force. Environmental dosimeters can also be used to measure the total dose at the periphery of the facilities

The use of ionizing radiation in industry is extremely diverse and the risk of exposure depends very much on the radiation sources used and the practices. It goes through fields as varied as: Gammagraphy -  Industrial radiography - Instrumentation gauges such as level, thickness, density - Smoke detectors - Sterilization of food and other products - Hydrology, such as leak detection- Dating of an ancient object - Detection of lead in paints in houses etc.
Here the risk of external exposure is variable. The workstation study carried out by the radiation protection officer, is essential to define the best dosimetric monitoring. Workers will wear a monthly or quarterly chest dosimeter, adapted if necessary for neutron radiation exposure. Additional end-dosimeters (rings or wrist) are recommended for hand exposure and the eye lens if the eyes or face are exposed. Environmental dosimeters will also be used to measure the environmental  dose in working areas in accordance with the regulations and standards in force.
