General information on radiation and nuclear environments
Action of radiation on measuring systems

What are the various environments in which radiation is encountered, and what measures can be taken?

• Our environment (soil, subsoil, atmosphere) naturally emits radiation and particles. The level of activity is generally low (since it is compatible with human and animal life). A typical order of magnitude dose rate in the Paris region, for example, is 10 µrad · h ^–1 (see units § 1.2 ).

  There are occasional regional (Massif Central) or continental anomalies, such...
