What Is Biodosimetry?

In radiation research, the dose must be accurately measured, otherwise the correct radiation chemical yield cannot be obtained, and the reaction process is difficult to control and reproduce. In radiation processing, the dose must be measured more accurately, otherwise the irradiated sample is not If it does not achieve the desired effect, it will be scrapped in batches. At the same time dosimetry is also very important in radiation protection.

Much literature is available on the design and calibration of research instruments for the determination of radiation dose. Dosages used in the fields of health physics, radiology, radiation chemistry, and reactor engineering, including a wide range,

Various physical and chemical effects produced by the interaction between ionizing radiation and matter have become the basis of radiation dose measurement. These effects mainly include: temperature effects caused by the absorption of radiant energy by materials, ionization effects of rays on matter, chemical effects, and physical properties of solid substances Various changes and so on. Based on this, common dose measurement methods such as calorimetry, ionization chamber and chemical dosimetry have been developed. Below we will discuss the commonly used dose measurement methods.

There are basically three methods for determining the dose of ultraviolet radiation:

Biological dosimetry: based on observation of skin or mucous membrane response to ultraviolet radiation; ^[3]

Photophysical method: Phototube method, fluorescent method, etc. are all such measurement methods;

Photochemical methods: oxalic acid method, potassium iodide method, etc. belong to this category.
