Non-chance derivatives of the aminotriphenyl-methane dye family can be produced as radioactive transformation agents: that is, they change from non-colour to dark blue as the absorption dose increases. The fwt-60 series uses hexahydroxyethyl (hydroxyethyl) ammonium triphenylethrin (hhevc) dyes. These dosages can be easily analysed using photometers or spectrometers. Fwt produces radiochromatic readers designed to analyse its dosages. Common wavelengths of 510 nm and 600 or 605 nm. These wavelengths together cover the entire measurement range of the dosage。
Fwt-60 radiochromagnetic dose, fwt-60 dose film specification parameters
Dosimeter type: radiocolored film
Dose range: 0. 5-200 kgy (0. 05-20mrad)
Dosage rate dependency: range of dose rates above 10e12gy/sec (10e14rad/sec)
Inherent sensitivity: the response value (changes in the absorption light divided by thickness) is not related to the unit thickness. A thickness calibration applies to all thickness。
Peak visible wavelength: 605 nm
Target wavelength: 510 nm and 600 or 605 nm
Color time: usually within 1 hour
Colour change: no exposure: transparency; after exposure: deep blue
Uv sensitivity: visible when exposed to ultraviolet light with a wavelength of less than 350 nm。

The radiation discoloration thin membrane dosage measurement techniques have several advantages compared to traditional photo films: simple operation, no dark room equipment and film dark boxes, and no subsequent shampoo treatment; dose response unrelated to dose rates; and energy response characteristics (except for low energy x rays below 25 kv). However, the film needs to be protected against extreme environmental conditions such as high humidity and high temperature. The radiation colour change film is applied to high-dose measurement scenarios, extending from the gorye level to hundreds of thousands of grays, such as the fwt-60 radiation colour change film produced by far west technology, goretta, california, united states; it should be noted that the dose response of the film to non-linear deviations requires correction between high-dose zones
