Nuclear Power Engineering The half life period of a radioactive substance is best determined by counting the number of alpha particles emitted per second in a Geiger Muller counter from its known quantity. If the half life period of a radioactive substance is one month, then It will completely disintegrate in two months 3/4th of it will disintegrate in two months L/8th of it will remain intact at the end of four months It will completely disintegrate in four months It will completely disintegrate in two months 3/4th of it will disintegrate in two months L/8th of it will remain intact at the end of four months It will completely disintegrate in four months ANSWER DOWNLOAD EXAMIANS APP
