Radiation & Health
What radiation is, dose, and the LNT vs. hormesis debate over low-dose effects.
Core concepts
Radiation, dose, and units
Settled scienceWe live in a gentle, natural bath of radiation every day. Understanding dose and units is liberating — it shows how much nuclear fear comes from unfamiliarity rather than real risk.
Low-dose radiation: LNT vs. hormesis
ContestedRegulation assumes any dose is proportionally risky (LNT); a large body of research suggests low doses are essentially harmless. A genuinely open question — and the optimistic, well-supported reading is that low-dose risk has been overstated for decades.

Common misconceptions
Myth: Any amount of radiation is dangerous.
Reality: We live in constant natural radiation; whether tiny added doses matter is genuinely unsettled.
Myth: Living near a nuclear plant gives you a big radiation dose.
Reality: The dose is a tiny fraction of natural background — less than a cross-country flight.
