Location Carlsbourg - Belgium

- The native terrestrial radioactive background radiation is recorded using a detector connected to a computer running the "Rad" software. This computer is connected to the Internet. "Rad" automatically sends (every 30 minutes) the reading of external radiation to the web server which hosts this site.

 

- The Carlsbourg station uses the international system (SI) unit of radiation which is µSv (micro Sievert) and µSv / hour (µSv / h) for the dose rate. (Cs137 / Co60)

 

- The Geiger counter works by detecting the ionization produced by a radioactive particle and recording it. The number of ionizations recorded over a period of time indicates the amount of radiation present. This is often done in one minute time intervals, resulting in the "beats per minute" or CPM. The higher the CPM, the higher the radiation levels ...

 

Gamma dose rate of the last 24 hours

Understanding the "Last 24 Hours" chart

 

  • The title "Dose Rate": Indicates the last current value read
  • On the y-axis: the scale provides the dose values for the last 24 hours (µSv / hr)
  • On the abscissa: the scale indicates the space time by 30 minutes of the last 24 hours
  • "Average, Mean" indicates the average of the doses received during the last 24 hours
  • "Min" is the minimum dose over the last 24 hours
  • "Max" is the maximum dose over the last 24 hours

An average dose rate of 0.13 µSv / h corresponds to an average level of exposure to natural radioactivity of 1.14 mSv / year. (1 mSv = 1 000 µSv = 1 000 000 nSv).

This corresponds to the natural radioactive background radiation for the Carlsbourg station.

Monitoring

The data for this graph is obtained using a geiger counter connected to a PC. The counter is manufactured by Black Cat Systems, Model GM45.

Radiation Monitor commissioned 1 Nov 2011.

Calibration

The GM45 probe was recalibrated July 2022 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.
