What Geiger counter??

HobGoblyn:
Had to have a test done at hospital last week. Had to eat radioactive porridge, then them scan me at various times over the next 5 hrs.

They said it’s perfectly safe, but I must avoid contact with children and pregnant women for the next 5 days……

Maybe if people had done that in Europe after the Tchernobyl disaster, while authorities claimed there would be no risk, there would have been fewer cancer cases. Who knows. ::)

"safe" as in within their guidelines for an acceptable increase in your lifetime cancer risk. Avoiding people? That's so they can also meet their "safe" guidelines for exposure to the public.

If you are really interested, ask the medial provider for the radionuclide, total activity, and your dose/exposure (this is all routine information for them that will be recorded against your medical records).

Rebonjour

The WWII/Cold War surplus gigers have some with Beta window (mica, super fragile) on the cylnder geiger tube so both Beta and Gamma sensitive.

Typically need to clean up leaked battery compartment, fix frayed cables.

Search CD/Navy alpha/plutonium survey Geiger etc.

Perhaps $50..200 ea.

For Alpha, DIY! See the science fair Spinarthascope...


here is apaer on Silicon Alpha detectors...

You can get a ZnS screen anbd eyeball it with a jewlers loupe...OR  build a sensitive photosensor/photomultiplier.

ZnS or other scintillator must be exposed direct to the Alpha source, ever a few " air or piece of paper stops the Alphas.
