Type of radioactive decay which has occurred is an alpha decay.
Explanation:
Type of radioactive decays:
Alpha decay is defined as the decay process in which alpha particle is released. In this process, a heavier nuclei decays into a lighter nuclei. The alpha particle released carries a charge of +2 units and a mass of 4 units.
Beta decay is defined as the process in which beta particle is emitted. In this process, a neutron gets converted to a proton and an electron.
The released beta particle is also known as electron.
Gamma decay In this process, an unstable nuclei releases excess energy by a spontaneous electromagnetic process and gamma -radiations are emitted. These radiations does not carry any charge and are electrically neutral.
The result indicates that taking calcium has no effect on the development of osteomalacia in the women. This is because, of the over 120 women placed on the calcium supplements, it happens to be minimal number of people ( less than 20 people) that develop the osteomalacia disease of the bone.
