1. Consider two monoenergetic photon beams with the same photon fluences. In one beam the photons are 100 keV and in the other they are 1 MeV. Determine the most appropriate relation between both exposures (X).
2. Electrons with kinetic energy of 1.0 MeV have a speci c ionization in air of 6000 IP/m whereas alpha particles of 2.0 MeV have an LET in air of 0.175 keV/μm. What value is closest to the ratio LET(alphas)/LET(electrons) in air.
Can radiations like gamma rays and x-rays be made prevented to enter a place by a magnetic field? Ans) Rutherford noted that gamma rays were not deflected (or at least, not easi
what is virtual displacement?and how is it different from actual displacement?
Their resistivity is very low and temperature coefficient of resistance is not constant. These are materials with unfilled or overlapping energy bands. Current carriers here are fr
BCS theory (J. Bardeen, L.N. Cooper, J.R. Schrieffer; 1957) A theory put forth to describe superconductivity and superfluidity both. This recommend that in the superconducting
A data transmission rate; the maximum amount of information (bits/second) that can be transmitted along a channel is called band width.

about beam intersection in gama and alpha beam?
actually in my college we are going to celebrate department function for physics we have to keep demos in physics for a project but i don''t have any idea will u help me
