Do you know the harmofradiation to the human body? After the human body is exposed to a certain dose of ionizingradiation, it can produce various biological effects that areharmful to health. According to the spatial characteristics ofthe effect, it can be divided into somatic effect, genetic effectand embryo effect. According to the time of effect, it can bedivided into acute effect and chronic effect short-term effectand long-term effect. Detection Scenes: Nuclear radiation instruments can be used for industria radiation, medical-device radiation, food/metal radiation Protection in daily life environment and other fields. The doses produced in different environments have different degrees of harm to the human body.<br><br>Three Warning Modes:Real-time digital display,Analog bar display, Vibration prompt 2000mAh Lithium Battery:Built-in large-capacity lithium battery, long battery life Using Type-C fast charging Radiation Sensing Area:Energy range:48keV-105 Mevs 30% Sensitivity:80 CPM/uSv Colour:Black Material:Plastic<br><br>Package Contents: 1 * Detector<br><br>Only the above package content, other products are not included.
