Hello everyone,

I have tried to found where can I get a Beta light, described in the survival kit in Wiseman's Book on Survival.

I have read that these glow indefinitely, is that true?

Please provide supplier name, address or phone, and of course e-mail or website

Thanks
 
Betalights use the radionuclide H-3 to excite a phosphor and produce light. The half-life of H-3 is 12.3 years, meaning after 12.3 years half of the H-3 has dissappeared. The luminosity of a betalight will decrease faster than the H-3 decay because the phosphor also degrades over time.
