Radioactivity
Casues of radiaiton
-
In a x-ray it produces a lot of background radiation and when placing mats on top of our body is to stop unwanted radaition being exposed to our body
Rocks and soil produce radiation because some rocks are radicavitve and give out radicstive gas to us and leaving us exposed
We are all epxosed to background radiatio but when we are exposed it is at a small ammount of radiation
We can tell how much radiation we are epxosed to by using a dosimeter badge using photo films to detect how much radiation they are exposed to

Types of Radiation
Beta Minus -
0^ ¬-1 e
Moderatly ionisng and can go thorugh paper and cannot go through aluminum because how the ionisng is little bit strong

Atom
Protons, Electrons, Neutrons
-
Electrons -
There can only be 8 electrons in a shell from the second outer shell till as many electrons there are
-
Neutrons -
Nuetrons are charged are negativly and can work out how many there are by taking away the atomic number and atomic mass
Isotopes
Isotopes is the same element however it has a variation, it has different number of neutrons
