Abstract
The present invention provides a rotator Gamma radiation unit which adapts to medical Gamma systems especially. The radiation source bodies carrying sources can rotate by 360.degree. within a radiation protection case. The trace of the radiation line forms several rotating pyramids with tops at the common focus. In this way the single successive radiation in the stationary focus manner is changed to multiple-points intermittent radiation. Therefore, while ensuring the radiation amount, it is possible to decrease the number of the radiation sources and simplify the manufacturing engineering. In this way it is possible to kill the disease tissues at the focus, and prevent the nuclear radiation line from injuring the healthy tissues outside the focus.
