For protection against radiation leakage of neutrons, which is derived from a linear accelerator, polyethylene pannel of 20 mm thickness containing 10% B_2O_3 was placed inside the door of a radiotherapy room. This made it possible to diminish the leakage of neutrons by about 70%. Using various protective materials, containing boron and polyethylene mixed in different ratios, the effect of leakage raduction was studied. But in all cases, the results were essentially the same.
