The most widely used medical radioisotope, Technitium-99m (^99mTc), is a daughter product of β- the decay of ⁹⁹Mo. This research proposed a new target of porosity for the irradiation experiment. The ⁹⁸Mo wire was heated to synthesis the porous structure ⁹⁸MoO₃, activity, and time irradiated was investigated by theoretically calculating and simulating with MCNPX code. Then all of the investigations will be verified by irradiated experiment in Dalat Nuclear Research Reactor.
