Radioactivity Bench

Code: 4832.00

An easy to set up apparatus for radioactivity

With our Radioactivity Bench it is easy to measure the number of radioactive particles emitted by alfa, beta and gamma sources. It is also possible to verify the principle of radioactive decay that is the set of various processes by which unstable atomic nuclei emit subatomic particles.

Radioactivity Bench can be mounted on Altay Magnetic Board (code 4114.30)

EXAMPLE OF USE: Radioactive sources and effect of metal screens

Determination of Radioactive alfa, beta and gamma decay and study of shielding effect of metal screens

Altay Radioactivity bench is suited for an easy measure of the radioactive decay of the different sources supplied. Setting up the time interval to a specified value, the radioactive activity in becqerel (Bq) can be quickly measured applying the known physics laws. If a quantity of radioactive material produces one decay event per second, it has an activity of one Bq. Since any reasonably – sized sample of radioactive material contains many atoms, one becquerel is a tiny level of activity, numbers on the order of gigabecquerels are commonly seen.
With the different metal screens supplied is also possible to study the shielding due to different materials, for example lead, interposed between the radioactive source and the detector. In this way it is possible to verify the behaviour of various radioactive source in presence of different metal screening and understand, for examples, the principles behind the construction of bunkers.
