Alpha Radiation (Decay) • α

Was an ex-Russian secret service agent who “outed” the Russian secret service for it’s “unauthorized killings” of innocent people whom the government found disagreeable. He was fired, imprisoned, then released, and sought refuge in London England while continuing to speak out about the injustice of the Russian secret service and how there were criminals in there using it for their own illegal purposes. Years later he was poisoned by Polonium 210 in a cup of tea. In 23 days he was dead. His killer has never been found.

Beta Radiation (Decay) β • Notice – the mass is O because electrons don’t have a mass!

Gamma Radiation (Decay) • γ

Lots of Gamma radiation was released in the disaster at Chernobyl… - 336 000 people evacuated - Cost over 200 billion $ - Lethal dose of radiation is @ 500 röntgen (5 Gy) over 5 hours… the reactor let out 20, 000 röntgen per hour - 4 square km of pine forest in the immediate vicinity of the reactor turned brown and died - Covered the reactor with concrete dome People died of cancer and radiation sickness
