Nuclear Radiation
- The device in which nuclear fission can be carried out through a sustained and a controlled chain reaction is called a Nuclear reactor.
- Radiation is energy that is travelling, and it can be absorbed (for example, your skin absorbs UV radiation from the sun). Contamination is material that emits radiation that gets stuck to surfaces and can be transferred and spread by physical contact. Contamination can behave just like dust or glitter.
- There are many devices used to measure radiation. Among them are:
- Geiger-Mueller counters (also Geiger or G-M counter) which are simple, often handheld devices that can measure radiation when the gas in the tube becomes ionized from the radiation (i.e. the radiation knocks electrons around). The ionized gas allows a current spike to occur across the high voltage field in the tube, and is frequently used to produce an audible click.
- Film badges are small radiation detectors that radiation workers generally wear to measure their long-term (e.g., weekly or monthly) radiation exposure. After the exposure period of interest is over, the film can be developed and the total dose determined.
- High-Purity Germanium (HPGe) detectors that measure gamma rays and provide excellent information about the gammas’ energies. This enables the identification of what isotope is emitting the radiation.
