RAMDA
(Radioactive Aerosol Monitoring & Dose Analyzer)

Radiation measurement

KCL Test Report KOLAS-Accredited Calibration Report U.S. Patent Application Filed

Size	Measurement Module 150150313mm / Control Module 20015183mm
Weight	-	HS Code	-
Key Specifications	○ Particle size (≥0.3 μm) and number concentration (particles/L) ○ Energy range up to 2 MeV; resolution ≤5.27% at 662 keV
Application Areas	○ Cutting work sites

RAMDA is designed for real-time simultaneous monitoring of aerosol size distribution, particle number concentration, and radioactivity at cutting work sites. The system measures the size distribution, number concentration, and radioactivity of aerosols in real time and provides data rapidly. It can be flexibly installed under various environmental conditions. The system consists of a control unit and operating software. ·Control Unit: The control unit supports multi-channel operation, enabling data acquisition and control through a wireless communication network. ·Operating Software: The operating software visualizes data collected from the aerosol measurement unit and the radiation/activity measurement unit, allowing users to check necessary information in real time. It also provide detailed information on radioactive aerosols, enabling timely alarms and warnings for worker safety.

Application Areas	○ Packaging and Transport of Radioactive Materials ○ Interim Storage and Disposal

Incorporates multifunctional metal composite coating technology, improving durability, corrosion resistance, and gamma-ray shielding performance compared with conventional commercial storage containers (200 L and 320 L). Ensures the integrity of low- and intermediate-level radioactive waste (LILW) storage containers and enhances worker safety. The coating is applied to the entire outer surface (including both sides of the lid), excluding the clamp fastening area and the inner surface of the drum, imparting multifunctional properties across all exposed areas.
