In an electric field, I travel towards the positive. a) Gamma b) X-Rays c) Radio Waves d) Alpha e) Beta f) Ultra Violet Light 6) What am I? I am affected by both electric fields and magnetic fields. In an electric field, I travel towards the negative. a) Gamma b) X-Rays c) Radio Waves d) Alpha e) Beta f) Ultra Violet Light 7) Smoke detectors... a) contain a beta source b) contain an alpha source c) normally, beta particles ionise the air, causing a current to flow through the circuit d) normally, alpha particles ionise the air, causing a current to flow through the circuit e) In the event of smoke being present, the air ionises the radiation, stopping current from flowing and sounding the alarm f) In the event of smoke being present, the ions are absorbed by the smoke, stopping current from flowing and sounding the alarm 8) Carbon dating... a) Can be used to estimate the age of ancient species b) All living things contain Carbon-14 which is radioactive. c) When an organism dies it can no longer absorb carbon-14 and the amount starts to decrease through decay. d) can be used to calculate the exact age of ancient species e) All living things contain Carbon-12 which is radioactive. f) When an organism dies it can no longer absorb carbon-12 and the amount starts to decrease through decay. 9) Nuclear Fission... a) Releases 2 - 3 neutrons as a by product b) The joining of two small (light) nuclei to form a larger nucleus c) This process occurs in the Sun d) the splitting of large, unstable atoms into two or more atoms along with the release of energy. e) This process occurs in nuclear reactors f) Needs extreme pressure and temperature to intiate. 10) Nuclear Fusion... a) Releases 2 - 3 neutrons as a by product b) The joining of two small (light) nuclei to form a larger nucleus c) This process occurs in the Sun d) the splitting of large, unstable atoms into two or more atoms along with the release of energy. e) This process occurs in nuclear reactors f) Needs extreme pressure and temperature to intiate. 11) Irradiation is... a) is when a radioactive source is in contact with an object or person. b) The radioactive substance rather than the emissions are present. c) Protection from irradiation means stopping the radiation from reaching you. d) exposure to radiation e) The object remains radioactive until the radiation is removed or decays naturally. f) the same as contamination 12) Contamination is... a) is when a radioactive source is in contact with an object or person. b) The radioactive substance rather than the emissions are present. c) Protection from irradiation means stopping the radiation from reaching you. d) exposure to radiation e) The object remains radioactive until the radiation is removed or decays naturally. f) the same as irradiation 13) Background Radiation consists of... a) Medical radiation b) Radon gas from uranium sources within rocks c) Cosmic Rays d) Food and Drink e) Nuclear Power and Weapons f) Ground and Buildings
