Question

Why are nuclear radiations more dangerous than other forms of pollution?

Answer 1

Nuclear radiations survive for a long period, up to a hundred years, resulting in widespread effects to pollute the natural environment.

Answer 2

Ionizing (nuclear) radiation is especially dangerous because it directly breaks chemical bonds and damages DNA and chromosomes, causing acute illness, cancers and heritable genetic mutations, while radioactive materials and fallout can persist for decades to centuries, enter soil, water and the food chain, and continue to irradiate people both externally and from within, producing immediate and long‑term effects that are hard to reverse or clean up.
