Hi /sci/,
I'm planning to assess radioisotopes decay as a random number source.
The idea is to measure the time between 3 consecutive decay events using a scintillometer or a geiger counter. If the time between event 1 & 2 is smaller than 2&3, send a '1' bit. If the time Btween events 1&2 is greater than 2&3, send a '0' bit. Don't send anything if time is evaluated as equal.
My current problem is to find an as strong as possible α, β, or β- source (20'000 C/M would be sufficient for my use) which is also a low X & γ ray source, as it is easy to confine the three first types of rays.
α, β, or β- events should be at least 500 keV to be properly detectable by the detection equipment.
Once confined (in a 1/4" steel & boron alloy enclosure), the residual exposition MUST NOT exceed 1mSv per year to ensure safety and compliance with regulations.
Indeed, buying the material should not be subject to excessive red tape, no price limit.
This said, do you have any ideas of what could be selected for that?
