<prompt> Arrange the following radiation according to their tissue damaging propey from maximum to minimum:g-rays X-rays b - rays a- raysa- rays b - rays g-rays X-raysa- rays b - rays X-rays g-raysX-rays g-rays a- rays b - rays  <response>: Tissue damaging propey of any radiation from any radioactive material is solely dependent on the ionizing effect. The decreasing order of the ionizing activity is as follows: alpha b x-ray g. Alpha paicles haveapproximately four times the mass of a proton or neutron and approximately 8,000 times the mass of a betapaicle. Because of the large mass of the-alphapaicle, it has the highest ionizing power and the greatest ability to damage tissue. gamma and x rays, which are electromagnetic, indirectlyionizing radiation. These are indirectlyionizingbecause they are electrically neutral as are all electromagnetic radiations and do not interact with atomic electrons through coulombic forces.
