At PCE Instruments you will find three types of radioactivity meters: Alpha radioactivity meters, meters for Alpha, beta and gamma radioactivity radioactivity meters for human beings. It is very important to measure radioactivity as well as to classify radioactivity values. An example of Gamma radioactivity: Terrestrial gamma radiation is measured according to general values from 0,03 – 0,3 µSv / h (micro Sievert/ hour). This „normal“ oscillation range is conditioned by contents in the ground of natural radioactive elements such as uranium, potassium, etc... To calculate this factor, we have to include cosmic radiation. So, the maximum radioactivity content in the highest German mountain (Schneefernerhaus) will be 110 nSv/h approx |
