The natural terrestrial radioactive background radiation is recorded 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 the exposure (acute or chronic), the nature of the radiation as well as the location of the radioactivity (external exposure, internal, on the surface, etc ...)
Radiation from radioactive substances is widely used in industry for the control of manufactured parts, welds, wear, and in nuclear medicine for diagnostic purposes at low dose, and for therapeutic purposes at high dose to cure cancers. During the various uses of radioactivity, it is naturally advisable to follow the prevention, protection and control measures adapted to the level of radioactivity. (wikipedia)
The veracity of the results obtained is considered as a binding test of the hardware piloted through a personal website with essentially educational and experimental values and which commits only the author.
The data for this graph is obtained using a geiger counter connected to a PC. The conter is manufactured by Black Cat Systems, Model GM45.
Radiation Monitor commissioned 1 Nov 2011.
The GM45 probe was recalibrated July 2016 according to the Gamma-Scout. This is tested in an authorized institute by the state. Each unit is supplied with a certificate stating its serial number.
