Which state has lowest radioactive radiation level?How much?

Answer 1

The above answer is correct - there are no records to show radiation levels on a per state basis - assuming you mean the US states.

Its a rather meaningless question. Most radiation that we receive on the earth's surface is a combination of solar and cosmic radiation, and therefore states that are close to sea level will have less radiation. On top of that, do you mean gamma counts per second on a per area basis, or do you mean total radiation per state?

If you mean radiation from radioactive elements on a per area basis (square kilometers for example), perhaps Hawaii is very low as the dominant rocks there are basalts which are naturally low in uranium, thorium, and potassium - the 3 main radioactive elements.

If you mean total radiation, then obviously the smaller states would have less radiation, so you could try DC or Rhode Island.

In general, areas that have a lot of felsic igneous rocks exposed on surface will have more gamma radiation from natural radioactive sources than areas that are underlain by mafic rocks or limestone.

Answer 2

i dont think states have specific radiation levels so i dont know if there is an answer to your question....i would google it if anything and see what you get....
