The 201 T1C1 solution is used in Nuclear Medicine for myocardial visualization. 201 T1 is a cyclotron‐produced radioisotope, obtained indirectly from the decay of 201 Pb or directly by irradiating mercury with protons. In this work, 201 T1 was obtained by irradiating a natural mercury target with protons in the energy range of 24 to 19 MeV, using the IPEN's CV‐28 cyclotron. Range calculations of protons in the targets and in the materials used to degrade the proton beam energy were made. At the end of the bombardment of a 329 μm thickness (6 MeV thickness) target of natural metallic mercury with 19 MeV protons provided a yield of 10 MBq 201 T1/μA.h.
