Medicine
Gamma rays are used in medicine to kill and treat certain types of cancers and tumors. Gamma rays passing through tissue of the body produce ionization in tissue. Gamma rays can harm the cells in our body. The rays can also detect brain and cardiovascular abnormalities.
Industry
Gamma rays can be used to examine metallic castings or welds in oil pipelines for weak points. The rays pass through the metal and darken a photographic film at places opposite the weak points. In industry, gamma rays are used for detecting internal defects in metal castings and in welded structures. Gamma rays are used to kill pesticides and bugs in food. Gamma rays are also used in nuclear reactors and atomic bombs.
Consumer goods
Gamma rays are often used in the food industry. The radioisotopes preserve foods. Although the rays never come in contact with food, beta radiation kills various organisms, such as bacteria, yeast, and insects.
Science
Gamma rays can be used to detect beryllium. They also played a very important role in the development of the atom bomb.
NO, X ray cannot be done on metal
It is unclear what you are asking, but the hazard from all CRTs is that they emit x-rays (an x-ray tube is a special purpose type of CRT designed for the one purpose of generating as much x-rays as possible). In CRTs used for displays the glass is leaded to reduce the level of x-rays to a "safe" level, but depending on the exact tube used these x-rays can still reach from 1 to 3 feet from the tube. Most are less than that.
cathode rays can emit electrons anode can collect them
yes!
Cathode rays are electrons.
