gamma x rays

. Similarly, if the radiations given out by a radioactive substance are subjected to an electric field perpendicular to their path, they separate into three constituents. Those which turn towards the negative plate are the positively charged alpha particles. Those, which turn towards the positive p..

Emission of a and b -rays bring some changes in the nucleus of the atom and the new element formed as a result of these charges is called daughter elemen..

They are electromagnetic radiations like X-rays having very short wavelength, in the range of 10 -10 m to 10 -13 m. They affect photographic plate. They are unaffected by electric and magnetic fields. Their ionizing power is low, (about one hundredth of b - particles). T..

In 1895, Wilhelm Conrad Roentgen, a German physicist observed, while doing some experiments with the discharge tube, that when cathode rays are allowed to fall on a metal target called anticathode placed in their path, a new kind of rays are produced. These radiations are called..

That part of the electromagnetic spectrum with the wavelength range 10 - 8 m to 10 - 1 2 m are called as X-rays W.C Roentgen, a German physicist discovered X-Rays in the year 1895. A photographic film wrapped in black color paper was found to be exposed when placed near a ..

X-rays and scanners help doctors to learn a great deal about the body as they reveal defects and abnormalities and thus contribute to diagnosi..

This has created a revolutionary change in medical sciences. It can take pictures of fractures in bones and diagnose problems such as lung infection et..

X-Ray Study of Crystals - In a crystalline solid, the constituent particles (atoms, ions or molecules) are arranged in a regular order. An interaction of a particular crystalline solid with X-rays helps in investigating its actual structure. Crystals are found to act as diffract..
