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