Radioactive Salt Substitute - potassium chloride

This video shows very low levels of radioactivity from potassium chloride salt substitute being measured with a simple geiger counter with a pancake probe.

The radioactivity seen here presumably comes from small amounts of naturally-occuring radioactive potassium 40 contained in the salt substitute. The radiation here is very low, and is not considered hazardous. Accordimg to Wikipedia, potassium 40 is found naturally inside the human body causes more than 4000 counts per second of radioactivity (more than 240000 CPM), hundreds of times more than what is measured here.

Glad to hear your new geiger counter is on the way -- I look forward to some top-notch videos, especially with the new video camera. You ought to get a modern Canon DSLR with video capability and an old (cheap) 55mm f/1.8 Super Takumar + M42->EOS adapter. That way you can make your videos with a radioactive lens.

My Inspector EXP, same model, is on the way (finally) and I want to see if I can reproduce this. I only get 30-50 CPM, normally off of my CRM-100 using the same salt.

My math shows the Inspector at 8 times more sensitive than may CRM-100, but most people say it is only 3 times. Time will tell. lol

The Inspector EXP+ is awesome. I'm in love.
