WebHaving identified the three types of radiation, try moving each one away from the detector. You can quickly show that alpha is very short range, beta has a range of about 10 cm in air, and gamma gets weaker with distance but doesn’t come to a stop at any particular distance. WebSpace radiation is different from the kinds of radiation we experience here on Earth, such as X-rays or gamma rays. Space radiation is comprised of atoms in which electrons have been stripped away as the atom accelerated in interstellar space to speeds approaching the speed of light - eventually, only the nucleus of the atom remains. biology matters pdf
