To highly accurately estimate an exposure dose of a worker who performs work.SOLUTION: A work management device 100 comprises a dose calculation unit 115 that integrates a radiation dose from a radiation source irradiated to each surface constituting the surfaces of a 3D model that simulates the movement of a worker in a 3D virtual space that reproduces a work space, to calculate an exposure dose of the 3D model. The radiation dose irradiated to the surfaces may be calculated including attenuation due to any structure or shield that exists in the 3D virtual space and exists between the radiation source and the 3D model.SELECTED DRAWING: Figure 1 【課題】作業を行う作業員の被ばく線量を高精度に見積もることを可能とする。【解決手段】作業管理装置１００は、作業空間を再現した３次元仮想空間内における作業員の動作を模擬する３次元モデルの表面を構成するそれぞれの面に照射される線源からの放射線量を積算して、３次元モデルの被ばく線量を算出する線量算出部１１５を備える。面に照射される放射線量は、３次元仮想空間内に存在し、線源と３次元モデルの間に存在する構造物・遮蔽物の何れかによる減衰を含めて算出されるようにしてもよい。【選択図】図１
