This article provides textual and graphical parameter information about the YD-510 environmental-grade X and γ radiation dose rate meter. The detector types include both GM tube and scintillator. It is primarily used in environmental assessment and pre-assessment work, and is also suitable for supervisory departments to conduct on-site inspections during law enforcement, obtaining stable and reliable detection data.

The environmental-grade X and γ radiation dose rate meter is a radiation detection instrument with higher sensitivity and stricter certification standards compared to protection-grade dose rate meters.

Overview

The YD-510 Environmental-Grade X and γ Radiation Dose Rate Meter adopts a dual-detector system consisting of a plastic scintillator detector and a GM tube composite detector, featuring high sensitivity and a wide measurement range, enabling accurate measurement of γ-rays and X-rays. It utilizes a high-speed microprocessor and a 3.5-inch color touch LCD screen, making operation more convenient. It is widely used for monitoring and inspection in various X and γ radiation environments, including medical, disease control, environmental protection, metallurgy, petroleum, chemical, radioactive laboratories, industrial non-destructive testing, radiation processing, mining, and more. The instrument fully complies with the sensitivity lower limit and range requirements of JJG521-2006 "χ-γ Radiation Air Kerma (Absorbed Dose) Rate Meter for Environmental Monitoring." The instrument uses a single detector, combining high sensitivity and a wide measurement range, making it suitable for both environmental-grade X and γ dose rate measurement and protection-grade X and γ radiation monitoring.
