Abstract: The objective of the present invention is to provide a self-shield for a RI manufacturing device which can reduce weight. In the self-shield (6), a first layer (21) shields primary gamma rays (L1), a second layer (22) shields neutrons (L2), and a third layer (23) which is closer to an outer peripheral side than the second layer (22) shields capture gamma rays (L3). In this way, the second layer (22) is arranged on the outer peripheral side of the first layer (21), so the first layer (21) is arranged on a position closer to a target (T) than the second layer (22). According to this configuration, the volume of a gamma ray shielding material can be reduced. Therefore, the weight of the first layer (21) can be reduced. In addition, the neutrons (L2) pass through the first layer (21), so a deceleration effect of the neutrons (L2) can be obtained, and the second layer (22) can more effectively shield the neutrons (L2). Therefore, the second layer (22) can be formed thinner than a comparative example, and the weight can be reduced.
