A sample of radioactive material decays simultaneouly by two processes A and B with half-lives (1)/(2) and (1)/(4)h , respectively. For the first half hour it decays with the process A, next one hour with the proecess B, and for further half an hour with both A and B. If, origianlly, there were N_0 nuceli, find the number of nuclei after 2 h of such decay.

A radioactive material decays by simultaneous emissions of two particles with half lives of 1400 years and 700 years respectively. What will be the time after the which one third of the material remains ? (Take ln 3 = 1.1)

A radioactive nucleus can decay by three different processes. Half life for first process is 2 hours . Effective half life of the necleus is 4/3 hours. Find the half for second process in hours.

Two samples of different radioactive substances initially have the ratio of active nuclei 4 : 1 and then half lives are 12 hr. and 16 hr. respectively. Find the ratio of active nuclei of the two samples after 2 days.

A radioactive material decays by simultaneous emission of three particles with respective half lives t_(1),t_(2),t_(3) minutes.The time in minutes after which (1)/(3) rd of material remains undecayed is

Radioactive decay follows first-order kinetic. The mean life and half-life of nuclear decay process are tau = 1// lambda and t_(1//2) = 0.693//lambda . Therefore are a number of radioactive elements in nature, their abundance is directly proportional to half life. The amount remaining after n half lives of radioactive elements can be calculated using the relation: N = N_(0) ((1)/(2))^(n) Half life of .^(60)Co is 5.3 years, the time taken for 99.9% decay will be
