“I don’t make nukes in my basement, why should I care?”, you may ask. Well, if you’ve never thought about radiation protection at home, chances are that the concentration of a type of natually existing radioactive gas, radon, in your basement is many times higher than the acceptable level. The plot shown here is the radon concentration in the basement of a random house in Vermillion, SD, over several days. It is always higher than the level set by EPA. The owner never heard about radon and did not take any action to reduce the concentration. If you are alike, please consider following the advice from EPA.
Two undergraduate students from my class PHYS-332, Experimental Modern Physics, accept requests from individual residences at Vermillion, SD to measure the radon concentration in their houses for two days. We charge $20 dollars for each measurement, which is way below the market price. The money will be used to support research activities of undergraduate students.
