In very high doses, well beyond the levels used medically for radiation therapy or x-rays, it causes severe damage to the DNA and the structure of cells. They no longer respond or work as they were meant to, and when they replicate they become invasive.
radiation is a carconigen and I cuases mutation or mistakes in codeing of DNA so New cells become deformed or mutated,and a bunch of mutated cells is a tumor. which can be cancerous or not. if it’s cancerous it can come back after removed in surgury, and spread and be not good.
There are two types of radiation: ionizing and non-ionizing. There is no evidence that non-ionizing, longer wavelength radiation causes cancer (radio waves, etc.)
Short range radiation (ultra-violet and x-rays) and ionizing radiation (like alpha, beta, and gamma rays) cause cancer by damaging chromosomes.
Two ways. Direct exposure to hard gamma literally wilts the body. Not likely to happen to you unless you somehow make your way into a reactor, or stand too close to a nuclear weapon going off, neither of which are recommended practices.
But the real danger is in the alpha particles, components of fallout and incomplete filtering at plants. Alpha particles don’t have much of a radius of damage, but if they wander into your food, or tobacco leaf, then the tiny particles embed themselves in your tissue and after a while will serve as the seeds of cancer.
