The picture above shows the radiation releases that occur in the normal operations of the nuclear industry.
Ionising radiation: radioactive decay and nuclear fission release tiny particles, some short-lived, some lasting for thousands of years. This radiation pollution, unlike other pollutants, cannot be seen, heard, smelled, or tasted.
The normal releases of radiation by the nuclear industry occur at the stages of uranium mining, milling, uranium enrichment, through to the storage and eventual burial of nuclear wastes.
That’s assuming that there are no unusual releases – “incidents”, leakage from containers, transport accidents, failure of cooling towers in reactors etc.
And, of course – no theft of nuclear materials, terrorist actions, no use of depleted uranium in “conventional” wars, and no nuclear war
