| titleOfInvention | High specific activity cobalt-60 radioactive source for gyro rotary type radiosurgery treatment system |
| abstract | The utility model relates to a high specific activity cobalt-60 radioactive source for a gyro rotary type radiosurgery treatment system, which comprises a cobalt-60 radioactive core body, an inner cladding, a middle layer cladding component and an outer cladding component; the inner cladding consists of a stainless steel cylinder with an opening at one end and an inner cladding end plug, and the wall thickness of the end surface of the stainless steel cylinder is smaller than that of the side surface; the utility model discloses in tens piece of or even hundreds of pieces of radiation sources of dispersion concentrate and evenly distributed source storehouse, the tungsten alloy material that source storehouse skeleton is good for shielding gamma ray effect, and impoverishment uranium shielding stopper has good shielding gamma ray effect equally, has reduced the occupation space of radiation source in equipment, has reduced the weight of the source body, has simplified the flip-chip operation of radiation source, has improved the security. |
