Radiological dose measurement card as well as preparation and using methods thereof

Abstract

The invention discloses a radiological dose measurement card, which comprises a measurement label, a standard color code, a blank color code and a base plate. The measurement label, the standard color code and the blank color code are arranged at the base plate, the measurement label is manufactured by adhering a ray-sensitive film to an adhesive label, the ray-sensitive film is a small round colored sheet, and is 8-12mm in diameter and 0.5-1.0mm in thickness, and the ray-sensitive film is divided into five layers from the top down, wherein the first layer is an ultraviolet-protection film, the second layer is a polyester film, the third layer is a discoloring material, the fourth layer is another polyester film, and the fifth layer is another ultraviolet-protection film; and the blank color code has a color of the ray-sensitive film before irradiation, the standard color code has a color of the ray-sensitive film irradiated by Cobalt 60 with irradiation dose of 25Gy, and the adhesive label is rectangular, 40-50mm in length, 12-22mm in width and 0.2-0.5mm in thickness. By the structure of the invention, the preparation method and the using method, disclosed by the invention, are very simple and convenient, the radiological dose measurement card disclosed by the invention is light and thin, and measurement results can be intuitively judged.

Description

technical field [0001] The invention relates to a radiation dosimetry card, which belongs to a medical device combining biomedicine and radiation technology. Background technique [0002] Irradiation technology is widely used in the field of biomedicine, mainly including blood irradiation. Blood irradiation refers to a certain dose of radiation treatment on whole blood or blood components. Radiation mainly refers to gamma rays. Blood irradiation is currently the only method used to prevent transfusion-associated graft-versus-host disease. Although the current blood irradiator can adjust the dose at will, the actual gamma-ray dose absorbed by the blood is not necessarily the national standard dose (generally 25Gy). At present, the staff of blood banks and hospitals who irradiate the blood just use a pen to record the radiation dose used, but cannot really determine the actual radiation dose absorbed by the blood. Although there are gamma ray dosimeters now, they are not use...

AI Technical Summary

Problems solved by technology

Now the blood bank and hospital irradiation staff just record the irradiation dose with a pen after the blood is irradiated, but cannot really determine the actual irradiation dose absorbed by the blood

Although there are gamma-ray dosimeters now, they are not used by staff in blood stations and hospitals because of their high price and inconvenient use.

At present, there are also some domestic literatures reporting radiation indicator labels, but they are rarely used clinically because they require advanced scanners and software to analyze the radiation dose, and because they are expensive and inconvenient to use.
