Most elements have different isotopes but theres one or two ____________ ones. The other isotopes tend to be __________, meaning they decay into other elements and give out ___________. | stable radioactive radiation |
Radioactivity is completely random. Radioactive substances give out radioactivity from nuclei of atoms. | You cannot do anything to make decay happen. Cannot predict which ones will decay. |
Definition of background radiation: 3 things we recieve it from: | -radiation that is present at all times. -unstable isotopes everywhere(air,rocks,food), radiation from space called cosmic rays,man made sources such as dumped nuclear waste |
Radiation dose depends on ___________ and _____________. How likely you are to suffer depends on type of ___________ and ___________. The higher the dose the more likely you are to develop cancer. | location occupation radiation amount |
3 examples where radiation dose is high: | -areas with certain underground rocks e.g granite, especially if they produce radon gas which gets trapped in houses -high altitudes in planes, this increases background radiation due to more exposure to cosmic rays -underground e.g mines, increases because of certain rocks |
