The grams of strontium − 90 present on the land in the year 2065 are to be stated. The grams of strontium − 90 present on the land in the year 2085 are to be stated. Concept introduction: The elements whose nucleus decays spontaneously are known as radioactive elements. The decay is accompanied by the emission of alpha particles, beta particles, and gamma rays. All the elements which have an atomic number greater than 83 are radioactive. The half life of a radioactive substance is defined as the time taken by half of its atoms to decay.
