After 1 alpha and 2 beta emissions.

A small amount of solution containing a radioactive nucleide A""^(x) was administrated into the blood of a patient. The activity of the nucliede id 2xx10""^(3) dps. Its half life is 15 hours. After 5 hours a sample of the blood drawn out from the patient. It,s activity was 16 dpm per mL. Radioactive nuclide A""^(x) decays by beta- emission (42%), beta+ emission (58%) in the patient body. Then half life value of beta- decary path is

One gm of an element decays by beta -emission to 0.125 gm in 200 years . The half life period of the reaction is
