Description
Technical field
The utility model relates to a kind of novel for biological ionising radiation provides the lab setup of high-energy ray, and relating in particular to a kind of is the biological irradiation instrument of sigmatron that radioactive ray source, irradiating biological body and cell produce biological ionising radiation with the sigmatron.
Technical background
Discovering of radiologic medicine, hematopoiesis and immune system that ray can destroy body to the ionization radiation effect that biosome produces.Research confirms, and bone-marrow transplantation is the effective method of treatment animal acute radiation sickness.Therefore, use the means that the hematopoiesis and the immune damaging action of body also become bone-marrow transplantation research from radiation effect.In biomedical researches such as leukemic bone-marrow transplantation treatment, behind the tumour cell that leaves existence in the radiation effect elimination body of application of radiation line, carry out hemopoietic system and immune system that bone marrow cell transplantation is rebuild body, reach the purpose of treatment disease.Except bone-marrow transplantation, ray also is applied to biomedical research fields such as human genome, immunology, oncology, radiobiology, cell biological and microbiology to the ionization radiation effect that biological cell produces.For a long time, pin adopts gamma ray device (caesium or cobalt) that ray source is provided usually in the biomedical research field, biosome or cell is placed to shine under the radiographic source achieve the goal.But, the cobalt source (
60Co) etc. gamma ray device has following shortcoming with not enough: 1, the radioactive isotope systematic protection is difficult; 2, waste treatment problem; 3, need after the continual decay of isotope source to change; 4, the isotope dose rate is non-adjustable; 5, because isotopic harmfulness is national to shortcomings such as isotope source supervision and Equipment Requirement threshold high (need the room of lining with lead or take corresponding safe precaution measure), difficult popularizations, seriously limited it in the biomedical research Application for Field.
The principle of work that X ray produces is: when the filament energising of giving X-ray tube was heated to incandescent state, the filament surface emitting went out electronics, meanwhile; Make formation highfield in the X-ray tube after adding voltage (anode for just, negative electrode is for negative) for the X-ray tube two ends; It will force filament surface and near electronics thereof the negative electrode that flies out, and with great acceleration directive anode, when it collides anode beryllium target; Electronics is lost its kinetic energy by retardation motion suddenly, change X ray into.Because to have penetration capacity strong for X ray, the medical treatment perspective, take pictures and industrial flaw detection in existingly use widely.And at biomedical sector, because X ray has the effect of high-energy ionization radiation, it and material effect produce a large amount of secondary charged particle, and make the atomic ionization of material, produce strong biological effect; Hematopoiesis and immune system that ray can destroy body to the ionization radiation effect that biosome produces produce acute radiation sickness.Therefore, X ray pair cell, microorganism have strong damaging action, and its sterilizing ability is ultraviolet more than 2,000 times.Since X ray and gamma rays all be with light quantum as radiation source, the generation ionising radiation, the equivalent energy of both per units is worth identical (1Gy gamma=1Gy X ray).But; X-ray biology irradiation instrument is to utilize high-voltage generating device to produce high voltage; Act on and send X ray on the X spool biological sample is carried out irradiation, can reach and cobalt and the same irradiation effect of caesium radiation source, and can effectively protect operating personnel; Therefore, can with the biological irradiation instrument of X ray substitute the cobalt source (
60Co) etc. gamma ray device is accomplished ionization radiation effect, and is more convenient, be applied to the research of biomedical sector and using safely, thereby becomes the bright spot that X ray is used, and promotes the development of biomedical cause.
