The present invention provides an improved positron radioactive drug radiation shielding device, which achieves savings in space required to store a canister after dismantling the device. Furthermore, a tungsten sleeve is disposed within the canister, and functions in coordination with a syringe. The tungsten sleeve is able to block radioactive radiation released by radioactive drugs contained in the syringe. Moreover, a front cover and a rear cover joined to two sides of the canister enable a hermetically-sealed space to be formed within the canister, which increases the effectiveness of blocking the amount of radiation from the canister, thereby reducing danger to the human body from the radiation.
