What happens to half life of radioactive nuclei at very high temperatures?

What is Half life of a reaction ?

Define half - life of a reaction.

In one averge life - time of a radioactive nuclei,

Very high temperatures are measured by

Radioactive disintegration is a first order reaction and it's rate depends only upon the nature of nucleus and does not depend upon external factors like temperature and pressure . The rate of radioactive disintegration (Activity) is represented as - (dN)/(dt) = lambda N , Where lambda = decay constant , N number of nuclei at time t , N_(0) = initial no. of nuclei. The above equation after integration can be represented as lambda = (2.303)/(t) "log" ((N_(0))/(N)) Calculate the half-life period of a radioactive element which remains only 1/16 of it's original amount in 4740 years :

The half life period of the radioactive is ._15P^30 is

A radioactive substance is being produced at a constant rate of 200 nuclei/s. The decay constant of the substance is 1s^(-1) . After what time the number of radioactive nuclei will become 100. Initially there are no nuclei present ?
