Solution
Artificial radioactive substances can be produced by bombarding lighter nuclides with alpha particles, protons and neutron. The radioactive substances produces in this manner are called radioisotopes.
Radioisotopes can be used as:
(i) Rays from Radium produce satisfactorily improvement in skin diseases.
(ii) Radioactive Sulphur S35 helps to study advantages and disadvantages of fungicides.
