- radioactivity
- radioactive decay
- radioactive substances are substances that decay radioactively
- alpha radiation
- proeduces a helium nuclei also know as alpha parcticles
- beta radiation
- releases electrons also know as beta particles
- gamma radiation
- it is a high energy electromagnetic wave with a higher frequency than x-rays
- uses /emitters
- photographic film
- bananas are slightly reactive
- the sun
- rocks
- fission
- Nuclear fission splits 1 nucleus into 2 or more smaller nuclei. It usually happens in nuclear reactors.
- A neutron collides with a large nucleus and is absorbed. This creates an unstable nucleus.
- This nucleus then splits into fragments. This releases large amounts of energy and more neutrons. These neutrons can then collide with other nuclei.
- The energy released is used to boil water, which rotates a turbine. The turbine then turns a generator, which produces electricity.
- danger of radiation

- contamination
- the object becomes radioactive
