| | 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.
