General Science / Radon Gas

« on: 23/09/2022 22:02:13 »

I had been asked if I would like to take part in a Radon Gas experiment, and today received two little discs to place one in the living room and the other in the bedroom for three months.
Apparently, Cornwall has the highest record of Radon Gas, and although I had heard of tests, etc I really didn't take any notice until I received this request.

It states it can cause lung cancer and it apparently comes up through cracks in the floorboards etc, and Cornwall is rife with it because of all the granite and rocks in the County.

Does anyone else live in a Radon Gas area? are they going over the top, it certainly is scary to think this invisible gas is being breathed into the home.

I'm looking for reliable and more importantly fast recycling AA rechargeable for use on Canon strobes. What do you guys recommend?
