In the irradiation therapy of a wide local area such as to the retroperitoneal lymph node metastasis of the seminoma or to multiple lung metastasis, a double irradiation from separate two centers to two radiation fields has been used for decreasing the side effect in the patients. However, there have been some difficulties such as non-uniformity of the radiation doses and impossibilities of definite dicision of the whole radiation area by a linacgraphy. We have, thus, used an alternate irradiation system by applying X-rays to a half side blocked with a lead plate at the line of the center in the whole radiation area, and then to the another half. This system was compared with the double irradiation system used in general. In alternate irradiation system, spreading of the beam was negligible in the boundary area by blocking with a lead plate at the half line and a considerable unformity of the radiation doses could obtained with confirmation of the block line. The whole radiation area was also well certified with one X-ray film. Our system can be very useful for the wide local radiation.
