Problems solved by technology

The advantage of the former is that different doses, dose rates and LET irradiation can be performed, the irradiation dose is accurate, and the controllability is good, but the cost is expensive
The latter is cheap and requires relatively low technical requirements. However, due to the shutter-controlled dose irradiation method, it is difficult to meet our requirements for low dose and low dose rate irradiation.

Abstract

The invention discloses a rotary adjustable alpha-source irradiation device which is characterized by comprising a bracket, a rotary platform erected on the bracket, a plurality of sample culture dishes arranged on the rotary platform, a liftable alpha-source irradiation mechanism erected on the bracket below the rotary platform, wherein the rotary platform is driven by a motor. The rotary adjustable alpha-source irradiation device is reasonable in design, the irradiation dose on the cell is adjusted by adjusting the height of the irradiation source, the rotation speed of the sample platform and the angle of a sample outlet, the fabrication cost is low, the irradiation device can perform the linear energy transfer (LET) irradiation in different doses, and different dosage rates, the irradiation dose is accurate and the irradiation controllability is good.

Description

technical field [0001] The invention relates to a rotating and adjustable alpha source irradiation device, which is used to study the radiation effect of particles in cells and its mechanism. Background technique [0002] With the development of science and technology, people pay more and more attention to the hazards of low-dose and low-dose rate radiation in the environment. According to D.Brenner's calculation, the radiation of alpha particles emitted by radon gas and its progeny to the human body accounts for 55% of the total environmental radiation received by the human body. In order to study the radiation effect and mechanism of alpha particles, radiation biologists Various α source irradiation devices have been developed, which can be divided into two types: α particles generated by accelerators and α particles generated by radioactive sources. The advantage of the former is that different doses, dose rates and LET irradiation can be performed, the irradiation dose ...
