Abstract
The present invention discloses sterilizing method with radioactive source. Inside a warehouse with protecting wall, the cargos to be sterilized are stacked vertically around a water well with stored radioactive source, and the radioactive source is drawn to reciprocate vertically with one steel cable possessing one end fixed to the radioactive source and the other end connected to the rotation shaft of the lifting mechanism, with the motion speed being regulated with the lifting mechanism. The method is simple, reliable, high in energy utilization rate of the radioactive source and homogeneous in radiation onto the cargos.
Description
Technical field
The present invention relates to a kind of method with radioactive source radiation sterilization.
Background technology
Radiosterilization sterilization processing is to utilize ionizing radiation (comprising the particle beam that radioprotective that radionuclide produces and accelerator produce) interacting with material or material changes physics, chemistry or the biology that produces, and material or material is carried out the process of processed.Usually the radiosterilization sterilization mainly refers to
60The Co radiation source or
137The gamma-radiation that Cs produces carries out RADIATION PROCESSING to be handled.Make photographed object reach parasite killing, mildew-resistant, sterilization, sterilization, improve the health quality, food storage is fresh-keeping, purposes such as material property improvement.
China began so far from the fifties, and irradiation processing is to adopt the radioactive source that will be positioned in the protecting wall storehouse to rise to ground from the well bottom, is shone the goods pile around radioactive source, and radioactive source is the radiation treatment goods under static state.Because radioactive source length is 420mm * Φ 11.1mm, therefore can not be with illuminated goods pile very high, if the goods pile is very high, must cause the irradiation dose uniform absorption of goods not reach requirement.
Summary of the invention
The purpose of this invention is to provide a kind of simple and easy reliably, help improving the method with radioactive source radiation sterilization of the irradiation quantity of radioactive source capacity usage ratio and goods.
Method with radioactive source radiation sterilization of the present invention, in the protecting wall storehouse, employing is being preserved the well of radioactive source with illuminated goods from ground to roof direction pile around, utilize an end and radioactive source to fix, the steel wire rope that the other end is connected with the hoisting mechanism rotating shaft drives radioactive source and makes uniform motion up and down.
When the present invention has changed traditional radioactive source RADIATION PROCESSING, radioactive source remains static, irradiated goods also is the irradiance method of static pile, dynamic motion carries out irradiation to adopt radioactive source to do up and down at the uniform velocity, thereby make and can be stacked into the roof from ground according to goods pile height, movement velocity is according to being regulated by hoisting mechanism by the requirement according to goods.The inventive method is simple and easy reliable, has improved the irradiation quantity of the capacity usage ratio and the goods of radiation source effectively, makes the irradiation absorbed dose of illuminated goods meet the requirements of uniformity.
Description of drawings
Fig. 1 is that the inventive method realizes sketch map.
Specific implementation method
With reference to Fig. 1, the well 4 of storage radioactive source is arranged in the protecting wall storehouse, and steel wire rope 3 passes through the protecting wall on nearly roof and places on the pulley 6, and one end and radioactive source 5 are fixing, the other end is connected with storehouse hoisting mechanism 2 rotating shafts outward, and the rotating speed of hoisting mechanism is by control system 1 control.The predose radioactive source is housed in the well bottom surface, personnel can enter storehouse with goods 7 from ground to roof direction pile around well, according to what of irradiation goods, determine the goods piling height, can pile up a circle, also can pile up the 2-3 circle.
Personnel were withdrawn into the outer control room of storehouse after the goods pile finished, and drove steel wire rope by control system control hoisting mechanism, and radioactive source is risen to ground at the bottom of well, made uniform motion enforcement irradiation up and down between ground and goods peak.According to the height that goods is piled up, determine stroke and the per hour speed and the exposure time of uniform motion up and down.Hoisting mechanism can be a buncher.
Claims (1)
1. method with radioactive source radiation sterilization, the employing radioactive source radiation leaves the illuminated goods in the protecting wall storehouse in, it is characterized in that with illuminated goods from ground to roof direction pile the storage radioactive source well around, utilize an end and radioactive source to fix, the steel wire rope that the other end is connected with the hoisting mechanism rotating shaft drives radioactive source and makes uniform motion up and down.
