A GAMMA RADIATION UNIT BY ROTATING PYRAMIDAL FACE FOCUS MANNER

摘要

The present invention provides a rotatory gamma radiation unit which adapts to medical gamma systems especially. The radiation source bodies it carries can rotate through 360 DEG 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-point pulse radiation. Therefore, while ensuring the radiation amount, it is possible to decrease the number of radiation sources and simplify manufacturing engineering. In this way it is possible to kill the disease organisms near the focus, or prevent the nuclear radiation line from injuring the healthy organisms outside the focus.
