Deskripsi Produk
Description:
This sensor contains tiny amount of Americium 241 isotope.
Americium emits alpha particles and weak gamma radiation, alpha particles completely blocked by the casing of the sensor, gamma radiation however freely passes through the casing but due to very low energy around 60 keV quickly absorbed by air (maximum run through air 15cm).
It is a great source for checking gamma only sensitive Geiger counters, if you have such type of counter it will be impossible to test it with other sources which emit beta particles only.
It could be used to test gamma spectrometers as well.
Add a nice "hot" piece to your collection which emits alpha and gamma radiation.
SBM-20 tube based Geiger counter indicates 140 Counts per minute from this source with gamma filter applied (approximately 80 uR/h or 0.8 uSv/h accordingly).
