摘要： A lightweight neutron dosimeter is disclosed. The dosimeter comprises a cylindrical body acting as moderator, an active component acting as neutron detector and neutron filters. The neutron filters are formed by at least two crowns placed inside the moderator, a first of said crowns being placed adjacent to the active component and a second crown being placed between the first crown and an inner wall surface of the moderator. The first crown includes top and bottom caps to cover open ends of the first crown, the top cap having an opening to allow introduction of the active component therein and a thickness of the top and bottom caps being the same as the thickness of the two crowns. The first and second crowns comprises vertical ribbons, an area covered by the plurality of vertical ribbons in each crown, excluding the top and bottom caps, being comprised in a range between 50-95%.
