摘要： 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.

摘要： A general purpose high accuracy dosimeter reader (80) for determination of dose, based on comparison of a treated dosimeter (111) with a series of images of pre-treated dosimeter (114). A dosimeter undergoes noticeable changes, such as a color change upon treatment with certain materials, such as toxic gases and processes, such as ionizing radiation and sterilization is pre-treated. The dosimeter is imaged with an imaging device (115) and images of the dosimeter or the changes, are stored in an information storage device (118). In order to determine the dose, the treated dosimeter is imaged and the image is compared with the series of pre-treated images of the dosimeter. The closest match of the treated dosimeter with the pre-treated and pre-imaged dosimeter would indicate the dose.

摘要： Described is radiation sensitive imaging and dosimeter composition (20) containing a radiation sensitive material (21), e.g., a diacetylene (R-C=C-C=C-R', where R and R' are substituent groups) or a radiochromic dye, a polymeric binder (22) and optionally a solvent (23) and/or an activator (24). Radiation sensitive materials are incorporated into a moldable or castable material and are molded or casted into shaped-articles (100), such as coatings, films, fiber, plaques, rods and blocks. Upon exposure to high-energy radiations, radiation sentitive material develops color thereby producing a visible image. Because of the higher thickness, a significantly lower dose of radiation can be monitored and an image is produced in three dimensions. Materials, processes and usages for thick radiation sensitive devices are described. A thick block can be used for monitoring radiation dosages in the three dimensions.

摘要： Described is a multi-sensor radiation dosimeter system with (1) a self-indicating, instant radiation sensor and (2) a conventional radiation sensor for monitoring high energy radiations, such as X-ray, electrons and neutrons. Conventional radiation sensors, such as X-ray film, TLD (Thermoluminescence Dosimeters), RLG (Radioluminescence Glass) and OSL (Optically Simulated Luminescence), are highly sensitive but are not instant. In the event of a dirty bomb, nuclear detonation or a radiological accident, one needs to know the exposure instantly so proper precautions can be taken and medical treatment, if required, can be given to the victim. If a self-indicating instant sensor is one of the sensors, one would know the dose instantly, and dose can be determined with higher accuracy than by the traditional methods. This type of device offers the best of both technologies.
摘要翻译：描述了一种多传感器辐射剂量计系统，其具有（1）自我指示即时辐射传感器和（2）用于监测诸如X射线，电子和中子的高能量辐射的常规辐射传感器。传统的辐射传感器，如X射线胶片，TLD（Thermoluminescence Dosimeters），RLG（放射性发光玻璃）和OSL（光学模拟发光）都是高度敏感的，但不是即时的。在发生肮脏的炸弹，核爆炸或放射性事故的情况下，需要立即知道暴露情况，并采取适当的预防措施，如果需要，可以向受害者提供医疗。如果一个自我指示即时传感器是传感器之一，则可以立即知道剂量，并且可以以比传统方法更高的精度确定剂量。这种类型的设备提供了最好的两种技术。

摘要： Disclosed is a detector for monitoring a UV false positive from genuine X-ray positive of color developing radiation sensitive devices. A layer which can be scratched off and is opaque to undesired radiation but transparent to X-ray is printed on the sensor. If the sensor displays a signal (i.e., develops color), whether it is genuine or false positive can be confirmed by scratching off the opaque layer. If the signal is a genuine positive, the whole sensor will be uniformly exposed/colored including the area under the opaque layer. If it is a false positive, the area under the scratched off layer will be of lighter color than the rest of the sensor.

摘要： Disclosed is a device for monitoring one or more of integral value of time and temperature, UV light exposure and a pre-determined temperature of an item. The device is useful for monitoring items or materials which are sensitive to time-temperature, UV light and/or a pre-determined temperature. Radiation sensitive devices such as self-indicating instant radiation alert dosimeters (SIRAD) can be accidentally, inadvertently or intentionally over exposed to time-temperature, UV light and a pre-determined higher temperature. Such over exposure can provide a false positive or false negative signal. A device based on polymerization of diacetylenes and melting of partially polymerized diacetylenes, both of which are associated with color changes, are proposed as false positive, false negative, and tamper indicator.
