Lead and hot cell equipment are needed to perform radiochemical processes to extract the desired radioisotope from the hot target. The proper design and shielding of this equipment are important to reduce the radiation exposure of employees. In this article, based on the gamma rays emitted from the hot target used in the molybdenum-99 production process, the calculations related to the design of a suitable shield for a chamber with specific dimensions made of Barite Concrete to make a hot cell or made of Lead to make a lead cell, has been done. The simulation results with MCNP6.2 Monte Carlo code show that the shield thickness to limit the dose rate to 10 µSv/h, for making hot cell or lead cells equals 90 cm and 24 cm, respectively.
