Background radiation
- Background radiation Background radiation and CMBR do sound similar, but they are not the same thing
Although cosmic rays
- Although cosmic rays are also a contributing factor of background radiation
Background radiation
- Background radiation is the constant low-level radiation we are all exposed to on Earth every day
Section 2 of 4Half-Life & Risk
1
make sure that you don't have them
2
The mass of the sample decreases with each decay When an atom decays, it changes into another element
3
For short half-lives, the decays happen in quick succession, so the radiation is released in quick succession
4
Let's say that Sample A has a half-life of 1 second, and Sample B has a half-life of 1 hour, and each decay in each sample releases 1000 alpha particles
5
Sample A releases 1000 alpha particles each second, whereas Sample B releases 1000 alpha particles each hour
