Need help taking test now In determining the length of time radioactive waste should be stored before disposal in normal waste, the Isotope's half-life is considered. What
is a half-life?

OA. the time interval for a radioactive material to double in size

OB. the time interval for a radioactive material to decay its radioactivity by half

O c.
the amount of time it takes for a radioactive material to reduce in size by half

OD. the amount of time one's life is reduced if exposed to a radioactive material

O E.
the time interval for a radioactive material to delay its radioactive exposure by half
