Nuclear decay
| Question | Answer |
|---|---|
| has lowest penetrating power; paper stops it | alpha radiation |
| has highest penetrating power; lead or concrete partially stop it | gamma radiation |
| pioneer of radiation research | Marie Curie |
| used to detect radiation levels | Geiger counter , Film badge |
| has medium penetrating power; stopped by metal foil | beta radiation |
| decreasing levels of C-14 are used in this process | carbon dating |
| nuclear energy source created from splitting 1 unstable nucleus into many | nuclear fission |
| nuclear energy source from combining many lighter nuclei into 1 heavier nucleus | nuclear fusion |
| cancer and radiation sickness | negatives of radiation |
| detect and treat cancers | benefits of radiation |
| time it takes for 50% of a radioactive source to decay | half life |
| nuclear reactions with this element create much less nuclear waste | Throrium |
| nuclear reactions with this element produces lots of energy and lots of nuclear waste | Uranium |
| location of naturally occurring nuclear fusion | stars |
| element created by alpha radiation | Helium |
| type of reaction NOT affected by catalyst and cannot be sped up, slowed down or stopped | nuclear |
| type of nuclear reaction that makes up 10% of the world's electricity | nuclear fission |
