Radioactive Detection Device for Beta Gamma Radiation Measurement and Data Analysis Dosimeter Features: 3 in 1 EMF meter: One device for detecting electric field, magnetic field radiation, and temperature simultaneously. Alarm function: When the electric field exceeds 40 V/m or the magnetic field exceeds 0.4 µT, the device will trigger ble, visual, and on-screen alerts. Clear display: LCD screen shows real-time radiation value trends and provides radiation assessment to indicate whether current levels are within safe limits. User-friendly design: Compact and lightweight, easy to operate with one hand, suitable for portable and field use. Wide application: Suitable for home, office, and industrial environments; can be used to measure electromagnetic radiation from devices such as mobile phones, computers, TVs, refrigerators, and high-voltage power lines; also useful for testing the effectiveness of protective items like radiation shielding clothing and films.
