RAY-3000A Personal Dosimeter Alarm

Product Overview:

The RAY-3000A Radiation Alarm Meter is an intelligent, compact radiation monitoring instrument primarily used for detecting X-rays and gamma rays. It features low power consumption, high sensitivity, stable performance, simple operation, and a small size, making it wearable or pocket-friendly. Utilizing advanced microcontroller technology, it offers strong anti-interference capabilities and can operate in harsh environments.

II. Working Principle

When exposed to X and gamma rays, the detector outputs a sequence of pulses. The number of these pulses corresponds to the dose rate of the gamma rays. After input shaping, these pulses form standardized pulses of a certain amplitude, which are then sent to the microcontroller for complete digital processing.

III. Product Performance

1. Low power consumption, capable of continuous operation for 20 days under background conditions.

2. Measures radiation dose rate, displays dose rate, cumulative dose, and stores cumulative dose.

3. Features cumulative dose storage function; data is permanently saved and not lost after power-off.

4. Offers multiple dose rate alarm thresholds to choose from.

5. Provides three alarm modes for user selection: light alarm (L), sound alarm (S), and sound-light alarm (C).

6. High sensitivity, responsive even under background conditions.

7. Compact size, easy to carry.

8. Equipped with a GM compensation counting tube.

9. Includes an imported CR2450 button battery for enhanced safety and environmental friendliness.

10. Radiation intensity display method: digital display.

IV. Technical Parameters

1. The GM counting tube is compensated, improving low-energy response.

2. High instrument sensitivity, responsive to environmental background.      

3. Suitable for gamma and X-ray radiation scenarios.

4. Measurement range: Dose rate: 0.01μSv/h—100mSv/h      

Cumulative dose: 0.01μSv—999mSv

5. Energy response: <±30% (50KeV—1.3MeV)

6. Relative intrinsic error: -17% to 25% (137Cs)

7. Dose rate threshold alarm: Alarm thresholds are 0.5, 1.0, 2.5, 10, 30, and 50μSv/h.

8. The instrument features cumulative dose storage function. Data in the memory is permanently saved and not lost after power-off, supporting up to 1 million storage and erase cycles.
