Michael Downey is a Toronto writer specializing in science. If cows eat tainted grass, their milk picks up radioactive material which stays active for years. And they're already developed. Children are vulnerable in a way that adults are not. Other effects can be delayed for years or generations.
Radiation takes the form of high-energy rays and particles.
Beta rays for example, are fast electrons that lose energy as they pass through our cells. Improper rejoining of these DNA ends causes key sections of DNA to be lost. The Coalition for Peace and Justice is a chapter of Peace Action.
