The device assesses the current level of X-ray and gamma radiation and provides alarms if this level exceeds the values set by the user. On the one hand, it warns the user about the deterioration of the radiation situation, on the other hand, it allows him to leave the place with high radiation in time and undertake other measures to protect his body. The device assesses the value of received integral ambient dose of X-rays and gamma radiation and provides alarm if the value is above the threshold. This allows the user to control time of his location in areas with high radiation level and evaluate the health damage caused by radiation. The device allows to search the radiation sources and areas with high radiation level and to choose the safest way in case of passing through contaminated areas. Ability of the device to detect the fact of radioactive contamination of food allows the user not to eat it. Ability to measure radiation level on the surface of items allows, for example, to choose building materials with low radiation background. Operating modes GAMMA mode Main screen shows the measured value of intensity of gamma radiation. Additional screen shows the measured value of gamma radiation. The device assesses the current value of the ambient dose intensity and calculates the ambient dose of X-ray and gamma radiation. As well the device monitors the stability of the surrounding radiation environment. If the radiation level changes significantly, the device automatically starts new measurement. If the level is stable, the restart does not occur, and the statistical error is constantly decreasing. On the one hand, it allows the device to respond quickly to changes of radiation environment, on the other hand, provide values with a low level of statistical error. If the measured values of radiation intensity and dose are above the threshold, the device provides alarm message and changes color of LED display and displayed values. SEARCH mode Changing of analog indicator with increasing radiation level. Changing of analog indicator with decreasing radiation level. The search mode is aimed on search of radiation sources in the area. The device counts the number of pulses of the detector for a small fixed time intervals. In search mode results of the measurements have a higher statistical error but high reaction rate of the device on the changes of radiation level. The device evaluates radiation intensity in two time intervals - a "short" (in the last second) and "long" (its duration is set by the user in settings). Both values are displayed as two strips of analog indicator. Two green outermost stripes show the value obtained for the "long" period of time, gray stripe in the middle - the value for the "short" interval. In case of approaching to radioactive source, the central stripe is getting mostly longer than the green outermost stripes and in case of estranging - shorter. As well, search for radioactive sources can be done aurally by the frequency of clicks emitted by the device. By approaching to radioactive source the frequency of clicks increases. Alarm in this mode is not provided. DETECTION mode Screen of background measurement mode. Screen of the mode of radiation level measurement near the item. This mode is used to detect radioactive contamination of surfaces of items and food. Since radioactive materials that enter human body is much more dangerous than external sources, it becomes necessary to detect small deviations of radiation level near the item from the level of natural background. To obtain such deviations it’s needed to carry out longtime measurements (tens of minutes, hours). The method consists in carrying out two measurements with low level of statistical error in the same place. In the first measurement the natural background level in absence of the item is defined. The second measurement is performed in the presence of the item with minimum possible distance between the detector and the item. The device compares the results of both measurements and provides the conclusion on presence or absence of radioactive contamination of the item taking into account statistical error. ABOUT SHIPPING TIME: Please, don’t leave a low rating for shipping time in Detailed Seller Rating when you give us your feedback. We try to do all the best for our buyers. Shipping takes so long time (about 14-20 days to Europe and about 20 days to USA, Japan, Australia) because we send from other country. Please, ask about express shipping if you need item for a short time. Express shipping cost is expensive enough. So, we choose regular air mail to save your money on shipping cost.
