A the age of sample B the size of the sample C the temperature of the sample D none of these. A the age of the sample B the size of the sample C the temperature of the sample D none of these. The half life of a radio active substance is defined as he time in which the activity of radioactive substance becomes half.

Radioactive decay takes place only when the atomic nucleus becomes unstable and thus the isotope type is the only factor which affects the radioactive decay of any element. Hello For the effect on the half-life is it only affected by the 5 cap or is it also the length of the poly A tail. The half-life of a drug refers to how long it takes for it to become 50 percent less active in or eliminated from the bloodstream.
