Cumulative Exam Active 11 12 14 16 TIME REMAINING 02:31:57 Emissions from alpha decay require the least amount of shielding. Which best describes why the emissions from alpha decay are so easily blocked compared to the emissions of other types of radioactive decay? O Alpha decay releases visible light, which has less energy than the light released during gamma decay. O Alpha decay releases particles that have less mass and charge than the particles released during beta decay. O Alpha decay releases particles that have less mass and charge than the particles released during gamma decay. O Alpha decay releases particles that have more mass and charge than the particles released during beta decay.
