Radiation safety refers to all measures taken to protect man and his environment against the harmful effects of exposure to ionizing radiation: alpha, beta, gamma and X-rays.
Certain types of radiation(alpha, beta, gamma and X-rays) are called " ionizing " because they carry enough energy to cause a change in the electrical charge of the atoms they pass through (ionization). Exposure thus corresponds to the interaction of ionizing radiation with matter. Exposure is usually low, but in the event of an accident, for example, people may be exposed to high doses of ionizing radiation.
External exposure causes external irradiation. It can be controlled by the duration of exposure, the distance from the radiation source and the use of protective shielding.
A person exposed to an external source of radiation (such as an X-ray) will never carry the slightest trace of radioactivity.
Radioactive contamination is often defined as "the undesirable presence of radioactive substances on the surface of or within any medium, including the human body".
Contamination is necessarily the result of the dispersion of a radioactive substance, following, for example, careless handling.
Radioactive substances come from a wide variety of sources, and can be in solid, liquid or gaseous form.

The units of measurement for radioactivity and its effects are Becquerels (Bq) and Sieverts (Sv).
Becquerel :
The Becquerel is a unit derived from radioactivity. It is defined as the activity of a radionuclide that decays at the rate of one disintegration per second.
The Sievert :
The Sievert is a measure of the health effect of low levels of ionizing radiation on the human body. It is defined as the dose equivalent, or the amount of ionizing radiation needed to produce the same amount of damage to human tissue as one Gray (Gy) of X-rays.
The regulatory framework for protecting workers against the effects of ionizing radiation is based on harmonized national regulations, the Public Health and Labor Codes, and European Directives. This framework also follows the recommendations of the International Commission on Radiological Protection (ICPR).

The radiation protection officer is responsible for ensuring that people and the environment are protected from the harmful effects of ionizing radiation. This includes taking measures to minimize radiation exposure, such as using lead shielding or maintaining a certain distance from radiation sources. The competent person also endeavors to ensure that workers and the public are informed of the risks.
Understanding the role and missions of the radiation protection officer (PCR)
The implementation of surveillance, prevention, protection and access control measures in risk areas aims to prevent or limit the effects of ionizing radiation received by workers and the public.
Dosimetry is mandatory for all workers likely to be exposed to ionizing radiation (in supervised or controlled areas).
Dose readings are accumulated over a predefined period.
Several technologies co-exist: radiophotoluminescence (RPL), optically stimulated luminescence (OSL) and thermally stimulated luminescence (TLD).
Operational dosimetry is mandatory for access to controlled areas. Complementary to passive dosimetry, it uses an active dosimeter to measure dose rate and integrated dose equivalent in real time . The electronic personal device measures the amount of energy absorbed by the worker's body and displays it on a digital screen. The main advantage of this system is that it provides real-time information, enabling the immediate implementation of protective measures if necessary. This type of epd dosimeter is worn on the waist, at the level of the iliac crest, or on the chest, and must be worn at all times when working in a controlled zone. An alarm system built into the electronic dosimeter alerts the worker or the control center if the individual dose or dose rate reaches a certain level of radioactivity.
Portable neutron survey meter is used for contamination detection, enabling rapid and immediate on-site measurement of X-ray, gamma and neutron radiation. It provides additional support for the protection and safety of workers during operations.
