Abstract

The invention discloses a detector and a detection method for ultraviolet irradiation dose. The detector comprises a graphene oxide / photocatalyst composite sheet, a surface resistance measuring device, a calculation unit and an alarming device, wherein two sides of the graphene oxide / photocatalyst composite sheet are provided with a surface resistance measuring probe connected with the surface resistance measuring device, a signal output end of the surface resistance measuring device is connected with a signal input end of the calculation unit, and the calculation unit comprises a memory chipin which a surface resistance value-ultraviolet irradiation dose standard curve parameter is memorized. The detector is applicable to personnel required to detect ultraviolet irradiation dose, particularly applicable to self checking of personnel exposed in an ultraviolet environment for a long time, thereby protecting physical health of workers.

Description

[0001] technical field [0002] The invention belongs to the technical field of ultraviolet irradiation detection, and in particular relates to a detector for ultraviolet irradiation based on graphene oxide / photocatalyst composite material and its manufacturing method and application. [0003] Background technique [0004] Electron waves with a wavelength of 100-400 nm are ultraviolet rays, which are one of the invisible parts of the spectrum. The ultraviolet rays that can reach the ground have a wavelength greater than 290 nm, and ultraviolet rays shorter than 290 nm have been absorbed by the atmospheric ozone layer. In the production environment, when the temperature of any object reaches above 1200°C, ultraviolet rays can appear in the radiation spectrum, such as smelting furnaces, electric welding, gas welding, etc. Mercury quartz lamps and ultraviolet lamps can also emit ultraviolet rays. The effect of ultraviolet rays on the body is related to the wavelength of the ra...
