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： An indicator composition capable of changing color in relationship to its exposure to a temperature above and below a base line temperature and to the time of said exposure, for monitoring the time-temperature history of a substrate, depositable as a layer on said substrate, comprising a dispersion of either a binder comprising a reaction inert, neutral finely divided absorbent, in the presence of a reactant comprising a salt of an acid or an organic compound substituted by at least one moiety which, in ionic form, is an anion or a binder/reactant, comprising at least one solid organic polymer whose constituent units contain, as a covalent substituent, at least one moiety which, in ionic form, is an anion; as indicator, at least one acid sensitive pH dye and as activator, at least one base. This composition may be utilized to form a solid state device for monitoring integral values of time and temperature during storage of perishables. The device is a single solid indicating layer deposited upon a substrate. The time required for the color change and the activation energy of the device can be varied by varying the concentration and nature of reactants, catalysts, additives and polymeric binder/reactant matrix. The color change can be gradual or abrupt and exhibited as a continuous strip, as alpha-numeric symbol(s) or as a line array which can be read by a bar code reader.

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： 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）自显示即时辐射传感器和（2）用于监测高能辐射的常规辐射传感器，例如X射线，电子和中子。诸如X射线胶片，TLD（热释光剂量计），RLG（放射致发光玻璃）和OSL（光学模拟发光）之类的常规辐射传感器是高度敏感的，但不是即时的。如果发生脏弹，核爆炸或放射性事故，需要立即知道暴露情况，以便采取适当的预防措施，并在需要时向受害者提供医疗服务。如果一个自我指示的即时传感器是其中一个传感器，人们可以立即知道剂量，并且剂量可以比传统方法更高的准确性来确定。这种类型的设备提供了两种技术中最好的一种。
