uses of gamma rays

Beta particles deviate more than alpha particles showing that beta particles are lighter than alpha particles or vice versa. Gamma rays do not deviate as they are electromagnetic waves and hence have no charge..

. Nuclear radiation can produce burns, cancer, loss of hair, vomiting and destruction of blood cells. An overdose can cause death. Strict safety regulations are enforced to protect workers and the general public from dangers of radiation. Lead and thick concrete walls are used as shields ..

Radioactive elements are those, which emit invisible radiations of their own accord. This is called radioactivity. Some typical examples of radioactive elements are uranium, thorium, plutonium, polonium etc. Radiations emitted by radioactive elements consists of Alpha particles ( a -particles) ..

Question: The radiations absorbed by ozone layer are ______. 1. infra-red 2. ultra-violet 3. visible 4. gamma rays Answer: ..

It is a spontaneous emission or disintegration of an unstable nucleus resulting in certain radiations. The elements exhibiting this phenomena are called radioactive elements. e.g., radium, thorium, actinium, polonium etc. Radioactivity does not occur due to any external provocation and is a propert..

The positively charged particles were discovered by E.Goldstien. He modified the discharge tube experiments by using a perforated cathode and after evacuating the tube he applied high voltage across the electrodes. Apart from the usual cathode rays emerging from the perforation..

The optical microscopes developed in physics are extensively used in the study of biological samples. Electron microscope, X-rays and radio isotopes are used widely in medical scienc..

Radioactivity Spontaneous emission of active rays by certain unstable elements. Three types of radiations are: (i) Alpha particles He 2 + ion (Helium nuclei). (ii) Beta - rays - consist of electrons. (iii) Gamma - rays - High energy electromagnetic ..

The lens maker's formula can be derived for a concave lens in the same way. The ray diagram is as follows: ..
