Background
In the field of biological dose detection, all experimental researches related to ionizing radiation biological effects often need irradiation researches on blood, cell suspensions or experimental animals. In the past, blood irradiation experiments are often performed by directly placing blood collection tubes, EP tubes and the like which contain blood on an accelerator treatment couch or a radiation source irradiation table. However, this manner of illumination has several disadvantages. Firstly, the influence caused by the temperature change of the blood after the separation introduces a new variable for the experiment, and brings a certain uncertainty. Secondly, the sample to be tested directly contacts the diagnostic bed or the irradiation table, the scattering of the material to the ray is different from the human body, and the human body environment cannot be simulated to the maximum extent. Thirdly, the irradiation method can only give an accurate irradiation dose, but cannot obtain an accurate absorbed dose. The above factors inevitably influence the reliability of experimental conclusions.
The preparation of dose-response curves must be supported by reliable and accurate physical doses, and several points need to be noted: the position of the blood placement is easily dose-predictable and as far away from the radiation source as possible to be considered a uniform exposure. In order to balance the charged particles, human tissue equivalent material with sufficient thickness must be present around the blood sample, and the existing experimental equipment cannot meet the detection requirements.
