Select the correct statements among the following : A. Slow neutrons can cause fission in _ 92 ^ 235 U than fast neutrons. B. -rays are Helium nuclei. C. -rays are fast moving electrons or positrons.| D. -rays are electromagnetic radiations of wavelengths larger than X-rays. Choose the most appropriate answer from the options given below
A. A, B and C only
(A) Slow neutron can cause fission in _ 92 ^ 235 U than fast neutrons because fast neutrons are too quick so they scatter of atoms instead of being captured by them (B) -rays are Helium nuclei, is a true statement (C) -rays are generated when neutron is converted into proton by releasing electron or proton is converted into neutron by releasing positron. (D) -rays have higher energies as compared to X -rays. So they have smaller wavelength as compared to X-rays.
