Environmental Radioactivity From Natural Industrial And Military Sources
Put simply natural philosophy determined that every event no matter the size or significance must have a natural explanation. As per the report to the UN General Assembly in 2000 nuclear testing is the main reason for human exposure to radioactivity caused by man.

Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollutants the components of pollution can be either foreign substancesenergies or naturally occurring contaminantsPollution is often classed as point source or nonpoint source pollution. Radioactivity detected in urine over 48 hr after treatment accounted for 55 of the dose.
Coal is a fossil fuel used to produce power in the United States. Pollution can take the form of chemical substances or energy such as noise heat or light. Return to first table 2 note 2 referrer.
----- Environmental Acronyms Abbreviations and Glossary of Terms Source. Cosmic Rays and Other Natural Sources. These come from the outer space to our planet with intense radiation as their nature therefore causing radioactive pollution.
The major urinary metabolites were identified by HPLC and isotope dilution analysis as methoxyacetic acid MAA and methoxyacetylglycine accounting for 50 to 60 and 18 to 25 respectively of urinary radioactivity. Table 2 Note. The process of burning coal at coal-fired power plants called combustion creates wastes that contain small amounts of naturally-occurring radioactive material NORM.
Table 2 Note 3. Environmental radioactivity is produced by radioactive materials in the human environmentWhile some radioisotopes such as strontium-90 90 Sr and technetium-99 99 Tc are only found on Earth as a result of human activity and some like potassium-40 40 K are only present due to natural processes a few isotopes eg. United States Environmental Protection Agency Information Resources Directory Spring 1989 OPA 003-89.
