Radioactive Decay
Types of Radiation
-
Beta
-
-
During decay, the number of neutrons in the atom decreases by one, and the number of protons increases by one
-
Gamma
-
-
Penetrating power: can only be reduced by much more substantial mass, (ex. thick layer of lead)
Gamma decay reactions occur if the energy of the radioisotope’s nucleus is too high, and the resulting atomic number and atomic mass remain unchanged during the course of the reaction
Radiometric Dating
Definition: calculates the age of geologic materials by measuring the half-life of their radioactive isotopes radioactive element
Extra details:
When an isotopes half life is up, half your original element is gone

-
Definition: 'occurs when an unstable atomic nucleus loses energy by emitting energy in the form of emitted particles or electromagnetic waves, called radiation.'
