ALPHA, BETA, GAMMA & NUCLEAR HALF-LIVES

Master nuclear half-life, radiation types, and decay calculations!

USE THE POWERPOINT FOR HELP ON THIS WIZER. Match the nuclear radiation with the correct description. alpha helium atom beta releases an -e during decay gamma most harmful--electromagnet waves Put the correct description for each type of nuclear decay. alpha mass of 4; charge +2 stopped by paper beta -1 charge goes through paper; stopped by wood gamma no mass; no charge goes through paper, wood; stopped by concrete waves of energy Label the following graphic using the following terms: alpha, beta, gamma alpha beta gamma Which type of nuclear decay is illustrated by the following equation? gamma radiations alpha decay beta decay How are nuclear reactions used in medicines? radiation therapy PET scans Bone scans All of the choices are correct Sort the following examples in which nuclear reactions are used today. ENERGY nuclear power plants air craft carriers submarines INDUSTRIAL COMMERCIAL sterilization of food utensils smoke detectors airport runway markers exit signs MEDICAL PET scans Bone scans Radiation therapy Study the following nuclear decay equation. What is the final product? Which type of nuclear decay is illustrated by the following equation? gamma radiation alpha decay beta decay What is the product of this beta decay reaction? The half-life of cobalt-60 is 5 years. If you have 10 grams of Co-60, how much do you have after 15 years? 5 g 1.25 g 10 g Americium-242 has a half-life of 6 hours. If you started with 24 g and you now have 3 g, how much time has passed? 6 hours 12 hours 18 hours Iodine-131 has a half-life of 8 days. If you have 8 g of I-131 and 16 days pass, how much I-131 do you have left? 1 gram 2 grams 4 grams Tin-126 has a half-life of 100,000 years. How many years does it take to reduce a 100 g of Sn-126 to 12.5 g? 100,000 years 200,000 years 300,000 years If Iodine-151 (15153I) goes through an α,α, β sequence of decay, what would be the final product? 14350Sn 13555Cs 12349In Name the 3 types of radiation...(watch your spelling!) alpha beta gamma
