[ RadSafe ] What fertilizer - specifically????

[franz.schoenhofer at chello.at]

Don et al., 

I do not believe that tritium dials are a good object for demonstration of radioactivity - I hope you know that the weak beta particles are shielded by glass or whatsoever and cannot be detected by an external measurement device, whether it would be a "microR" -meter or a "microSv"-meter. BTW: I have experience with tritium from wrist watches and its incorporation into the human body.

Best regards,

Franz
