Albedo dosimeter encapsulation for measuring neutron and gamma radiation in at least two dosimeter zones, comprises a casing having cadmium or boron containing walls which have neutron absorbing capability. The casing has a front side which faces a radiation field and a rear side which faces a body which carries the encapsulation. The rear side of the casing is closed by a cadmium or boron containing rear wall having a first portion and a second portion. A cover is located at the front side of the casing and has a cadmium or boron containing wall portion and a window portion. The casing has a first zone for holding a first dosimeter means and a second zone for holding a second dosimeter means. The first zone is aligned with the cadmium or boron containing wall portion of the cover and the first portion of the rear wall. The second zone is aligned with the window portion of the cover and the second portion of the rear wall. The cadmium or boron containing wall portion of the cover has a neutron absorbing capability which is different from the neutron absorbing capability of the first portion of the rear wall. The first portion of the rear wall has a neutron absorbing capability which is different from the neutron absorbing capability of the second portion of the rear wall.
