ALPHA RADIATION is the radiation type thatis most easily blocked by barriers, even byclothing, paper, or the skin. Alpha radiationis the radiation type that is mostcommonly emitted by natural uran--m.( By contrast, Gamma ray radiation, is the"Macho" type of radiation. Gamma rayspenetrate all barriers, even metals suchas lead. Gamma rays make space traveldifficult, because cosmic rays in outerspace are mainly gamma radiation. Cosmicradiation at the ISS space station is 240times more intense than natural surfaceradiation on Earth; At the surface of redplanet Mars, the radiation is 730 times moreintense than Earth's surface radiation. TheGamma Ray Burst of October 2022, a tightlyfocused narrow beam, traveled 2.4 billionlight years to Earth; it was the mostintense energy event since the early"Big Bang." That GRB interrupted low-frequency radio on Earth for four days.)
