The leakage radiation through the shielding on an isocentric gantry of a neutron therapy machine was measured with a Rossi‐type proportional counter. The dose equivalent of the leakage radiation was determined at two positions: (1) in the plane of the patient and (2) in the plane of the target. The dose equivalent of the leakage radiation is approximately the same as the leakage of a high‐energy x‐ray linac.
