Radioactive Contamination Detector for Food and Water

RD45-2 Water and Food Radioactive Contamination Detector

The RD45-2 Water and Food Radioactive Contamination Detector measures the specific activity of 137Cs and 131I radionuclides in food and water, including various beverages. This instrument is ideal for enterprises, inspection and quarantine departments, disease control centers, and environmental protection agencies to conduct rapid detection of radioactive contamination levels.

Key Applications

Widely used in radiation monitoring and protection fields, providing reliable technical support for national counter-terrorism, nuclear emergency response, nuclear power plants, customs, and entry-exit inspection and quarantine.

Human-Computer Interaction

Background measurement and sample measurement modes
Four-button interface: power on/off, left, right, and confirmation buttons
Simultaneous display of real-time CPS, average CPS, and measurement time
Multiple measurement modes: background, sample activity, liquid, and solid
Configurable alarm thresholds, measurement time, system time, and alarm settings

Instrument Applications

Non-War Environments: Functions as an on-site radionuclide activity detector for nuclear waste disposal sites and radioactive contamination monitoring at nuclear leak accident sites. Also serves as a laboratory radionuclide activity analyzer for collected samples.

Wartime Environments: Used as an on-site monitoring instrument in nuclear war or radiation contamination zones to detect radionuclide activity levels and contamination severity.
