WebGiven the smaller quantities and its low-energy radioactivity, Sm-151 is less dangerous than Sr-90 and Cs-137 and can also be left to decay for ~970 years. Finally, there are 7 long-lived fission products. They have much longer half-lives in … WebThe radiation decay of a radioisotope results in formation of isotope of another element or same element, which can either be a stable or an unstable isotope. If the resultant isotope is unstable, further decay takes place until it becomes a stable element. The simultaneous decay of an unstable radioactive isotope is also called its decay chain.

Half-life (symbol t½) is the time required for a quantity (of substance) to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive. The term is also used more generally to characterize any type of exponential (or, rarely, non-exponential) decay. For example, the medic… WebThis shows that the population decays exponentially at a rate that depends on the decay constant. The time required for half of the original population of radioactive atoms to decay is called the half-life. The relationship between the half-life, T1/2, and the decay constant is given by T1/2 = 0.693/λ. la oveja shaun 2
