Isotope Half Lives and Energies
This page is not meant to be a comprehensive list of all information that is required to work safely with radiation. It is only a small fraction of isotopes available but it covers the commonly used isotopes in my research institute. I will add other data if requested though.
Isotope radiation information
|Isotope||Half life||Decay type||Daughter nuclide||Decay energy||Shielding required|
|Tritium (Hydrogen-3)||12.3 years||Beta||Helium-3||18 keV||No specific shielding required|
|Carbon-14||5730 years||Beta||Nitrogen-14||156 keV||No specific shielding required although thin perspex could be used|
|Phosphorous-32||25 days||Beta||Sulphur-32||1.709 MeV||1cm perspex or equivalent|
|Iodine-125||60 days||Gamma||Tellurium-125||Maximum 35 keV||Lead or other high density material|
