Radioactive progenies of thoron can be measured accurately, thanks to the PTB
This release is available in German .
Approximately one fourth of our annual radiation exposure we absorb by breathing within our own four walls. A relevant radiation source here is thoron, an isotope of the noble gas radon, which so far has been very difficult to measure. Researchers of t...
