I know nothing about fluid dynamics, but this is the only forum that I could find that discusses radiation.

I am a ham (amateur radio operator) that bought a Civil Defense Geiger counter at a hamfest, to be ready for a leak at my local nuclear power plant.

In my home the Geiger counter reads 100 to 150 Roentgrens per hour, using the X-10 scale. But according to the information that I found, this would have already given me a lethal dose of radiation:

I must be doing something wrong. Can anyone please help to understand this?

Thank you for your help.

Wikipedia says that in the X10 the Geiger counter counts from 1 to 50. How come yours is giving output between 100 and 150?
Another question. Is that thing properly calibrated?
