Fission vs. Fusion
-Uranium 235/236 (Fuels)
-Splits into Kr 92 and Ba 141
In which two or more atomic nuclei collide at a very high speed and join to form a new type of atomic nucleus.
Fission: -Lower energy released. -Fission is used in nuclear power plants. -Nature Fusion: -3 to 4 times greater than the energy released by fission. -Fusion is an experimental technology for producing power. -Stars, sun
Alpha, Beta and Gamma Radiation
-are least likely to penetrate skin, and is the least harmful
-alpha-emitting materials are only harmful if they are inhaled
-travels a short distance
-are faster than Alpha particles & can penetrate further
-will travel up to 10 meters before they are absorbed by the atmosphere
-examples of beta emitters: strontium-90, carbon-14, sulfur-35
-is the deadliest, and can penetrate just about any kind of shielding
-they can travel nearly a mile in the air
-examples: iodine-131, cesium-137, cobalt-60
-Beta radiation is not fatal unless exposed for prolonged periods
-Gamma radiation is the deadliest and can penetrate just about any type of protection
Exposure to ionizing radiation could cause radiation sickness which damages cells. There is currently no treatment to repair cells, however there are recently approved drugs that are effective at removing radiation elements from the body
- Some plants and animals are more sensitive to radiation than others. The common pine tree and many small rodents for exsample struggle greatly in a radioactive environment. This offsets the environmental balance, causing more of some organisms and less of others.
- Also the first 10-15 inches of soil are often contaminated. This makes it very difficult for plants and many ground organisms to grow and thrive.
