The natural terrestrial radioactive background radiation is recorded (Carlsbourg-Station) since November of the year 2011 "Fukushima Year" and until today. The data collected is regularly recorded in the database of a server. An annual graph is then published, as well as a graph showing all the annual data since the end of 2011.

Effects of radiation

The effects on a living organism of exposure to ionizing radiation (irradiation) depend on the level and duration of exposure (acute or chronic), the nature of the radiation as well as the location of the radioactivity, external exposure, internal...

Uses 

Radiation from radioactive substances is widely used in industry for the control of manufactured parts, welding, wear, and in nuclear medicine for diagnostic purposes at low doses, and for therapeutic purposes at high doses to treat cancers. During the various uses of radioactivity, it is naturally appropriate to follow the prevention, protection and control measures adapted to the level of radioactivity. (wikipedia)
