Explanation / Answer

a)                     Medical instruments are sterilise by using radiation beforethey use.in this process bacteria etc present in that equipmentwill be disposed by radiation.they will bedied
b) surface barrier detector ; G.Mcounter c) .         The holder maycontain a number of filters that attenuate certain types ofradiation, such thatonly the target radiation is monitored. To monitor gammarays or x-rays, the filters aremetal, usually tin or lead. Tomonitor beta particleemission, the filters use various densities of plastic.It is typical for a single badge to contain a series of filters ofdifferent thicknesses and of different materials, the precisechoice may be determined by the environment to be monitored. Theuse of several different thicknesses allows an estimation of theenergy/wavelength of the incident radiation.
