 For a comparison: Fish caught in the northern Baltic Sea have about 5 Becquerel, some Wild Boar shot in Bavaria have about 600 Becquerel, and the limit beyond milk may no longer be sold is 370 Becquerel. For regular food the limit in Germany is at 600 Bequerel. 1998 a Wild Boar was shot in Vosgues with 1.018 Becquerel. Some Algae along the Japanese coast have 10000 Becquerel. Field vegetables from the region of Fukushima have 8000-150000 Becquerel.
-Even though the radiation of that Thorium probe is rather weak in comparison, one should not incorporate (swallow or breathe in) dust particles from it, since the could have a long term effect on the lung tissue surrounding it. So I decided in favour of the Thorium mantle and against the Pitchblende stone, because the stone could loose some particles whereas the Thorium probe was well packaged.

 Normally, such a probe does not contain pure and singular isotopes but an entire series of isotopes with different radiation patterns. The [http://en.wikipedia.org/wiki/Decay_chain Thorium Decay Chain] only has Alpha and Beta decay, so some interesting experiments were possible with it:
