An important source of natural radiation is radon gas, which seeps continuously from bedrock but can, because of its high density, accumulates in the ground. References
Carcinogenesis and genetic damage such as changes in DNA are possible stochastic effects of radiation exposure. Gamma rays are often emitted along with alpha or beta particles during radioactive decay. It's much easier for me to learn a few basic concepts and then reuse code by text-editing the code that previously worked.
