About the sample
|This is a commercial sample bought from USA. The exhibited polonium belongs to our colleague Miha Bukleski. 210Po is an alpha emitter that has a half-life of 138.4 days. It decays directly to its stable daughter isotope, 206Pb. A measurement of radioactivity of this sample, at different distance, on 25 of January 2023, has been conducted with our colleague Lambe Barandovski .|
Distance/cm Radioactivity /Bq
In the International System of units (SI), the becquerel (Bq) is the unit of radioactivity. One Bq is 1 disintegration per second.
The next measurement of the radioactivity of this sample is scheduled for 25 of January 2024.
