Dose measurements at a point that is located in the radiation field netron, the detector must be in accordance with the radiation field because the amount of energy absorbed detector is not only dependent on the flux netron, but also on the type of intraksi that occur between netran and atom-atom mater ; detektor.Salah just one way to ilustrasl dose measurements will be discussed with the thermal netron gamma detector film.Hasbuna Kifli;Tenaga tetap pada Departemen FLsika F.M.I.P.A. lnstitut Teknologi Bandung.
