A newly prepared radioactive nuclide has a decay constant `lambda` of `10^(-6) s^(-1)`. What is the approximate half-life of the nuclide?

A radioactive uclide has a decay costant equal to lambda .Give the formula for the mean life of this nuclide.

The radioactive decay constant is 4.28 xx 10^-4 year^-1 . What is the half life period of it?

(a) Define the terms (i) half-life (T_(1//2) ) and (ii) average life (tau) . Find out their relationships with the decay constant ( lambda) . (b) A radioactive nucleus has a decay constant, lambda = 0.3465 (day) ""^(-1) . How long would it take the nucleus to decay to 75% of its initial amount?

The half life of a radio nuclide is 77 days then its decay constant is

The half life of a radio nuclide is 77 days then its decay constant is

A radio nuclide A_(1) with decay constant lambda_(1) transforms into a radio nuclide A_2 with decay constant lambda_(2) . Assuming that at the initial moment, the preparation contained only the radio nuclide A_(1) (a) Find the equation decribing accumulation of radio nuclide A_(2) with time. (b) Find the time interval after which the activity of radio nuclide A_(2) reaches its maximum value.
