Radioactivity was discovered my Antoine Henri Becquerel (accidentally) also Marie and<br />
Pierre Curie<br />
Nuclear radiation mostly studied by Marie Pierre as well with her husband<br />
With an unstable isotopes or radioisotopes<br />
When the atomic number is lower by two and its mass number is lower by four when an<br />
atom loses an alpha particle<br />
Equal mass number- superscripts<br />
Equal atomic number- subscripts<br />
Taking out or moving apart of a neutron in a atom is beta particle<br />
When it decays it gives of energy<br />
Zero charge in neutron<br />
When it give off a electron but the mass doesn’t change<br />
Alpha is the longest one but it wont go thru skin<br />
Alpha has a lack of neutrons<br />
Beta one of the neutrons splits<br />
The – charge give energy and the + charge becomes a neutron<br />
Beta will go thru your skin but to the germ cell<br />
Gamma is high energy<br />
Gamma is sort was cant go thru lead<br />
The particle is make is futons<br />
We humans are organic material<br />
radioactive isotope is carbon-14/not stable<br />
normal carbons it carbon-12 and 13/stable
