gamma rays nuclear

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..

. 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 ..

They are not deflected by electric and magnetic fields. They affect photographic plates. The ionising power is very low compared to alpha-particles and beta-particles. They are electromagnetic waves like X-rays and light rays. The wavelength of these rays ar..

. Hahn and Strassman discovered that when 9 2 U 2 3 5 is bombarded with thermal neutrons, it splits up into 5 6 Ba 1 4 1 and 3 6 Kr 9 2 with emission of three neutrons along with 200 MeV of energy per fission. This energy appears in the form of g -rays..

Nuclear Energy and Chemical Energy - Nuclear energy is released when very small particles of matter split or combine. After the split or combination, they result in small particles or heavy particle. The rest of the mass is changed into energy. This process of changing mass into..

Artificial Nuclear Reactions - Radioactivity is broadly classified into two categories: a) Natural radioactivity and b) Artificial or Induced radioactivity. If a substance emits radiations by itself, it is said to possess natural radioactivity. If a substance does not possess radioactivit..

Emission of a , b and g Rays - 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 element. There is conservation of both atomic number and mass number in the equation of a nuclea..
