    • Described as a self-indicating instant radiation dosimeter (1001) for monitoring high energy radiations, such as X-ray. The dosimeter contains a radiation sensitive, color changing, indicating composition (10), e.g., a diacetylene (R-C=C-C=C-R', where R and R' are substituents groups) or a radiochromic dye, a polymeric binder (20) and optionally a shelf life extender (50) or an activator (40). The radiation sensitive composition (10) changes color instantly when exposed to high energy radiation. The dose is estimated by comparing the color with a color reference chart or more accurately with a spectrophotometer or an optical densitometer. The radiation sensitive composition (10) is protected from low energy radiation such as UV light, by a layer of low energy absorbing materials, such as UV absorbers.
    • 描述为用于监测诸如X射线的高能量辐射的自我指示即时辐射剂量计(1001)。 剂量计包含辐射敏感的颜色变化的指示组合物(10),例如乙炔(RC = CC = C-R',其中R和R'是取代基)或放射性色素染料,聚合物粘合剂(20) 和任选的保质期延长剂(50)或活化剂(40)。 辐射敏感组合物(10)在暴露于高能量辐射时立即改变颜色。 通过使用分光光度计或光密度计将颜色与颜色参考图比较或更准确地估计剂量。 辐射敏感组合物(10)通过诸如UV吸收剂的低能量吸收材料层来保护免受诸如UV光的低能量辐射。

    • PURPOSE: To form a simple and convenient measuring device for absorbed dosage by measuring change in absorbance by a sharp light source with a single wavelength utilizing a hollow cathode lamp wherein manganese, lithium, and the like are used as a negative electrode material.
      CONSTITUTION: The sharp single light with a single wavelength emitted from the hollow cathode lamp 3 wherein manganese, lithium, and the like are used is irradiated on a sample 5 through a filter 4. The transmitted light is inputted to a computing part 7 via a photoelectric doubling tube 6. The change in the absorbance which is proportional to the absorbed radiation quantity is obtained, and the absorbed radiation quantity is computed and displayed on a display 8. Manganese emits two sharp light beams of wavelengths, 279.48nm and 403.08nm. The former is suitable for a triacetic acid cellulose fim dosimeter, and the latter is suitable for cabalt glass dosimeter. The light of 670.08nm from lithium is suitable for a blue cellophane dosimeter. By using the hollow cathode lamp which emits the single wavelength light suitable for the individual dosimeter, the simple measuring device without a spectrometer can be constituted.
