Detection system for ionizing radiation emitted by sources such as radiopharmaceuticals, radioactive samples, and similar materials, which generates an electrical signal following the interaction of detection sensors with contaminating agents.

Technical features

The technical features of the patent include an innovative system for detecting ionizing radiation from sources such as radiopharmaceuticals. This system accurately determines the position and spatial appearance of radioactive sources, even in confined areas like the human body.

In the event of radioactive exposure, the sensors activate LED indicators, illuminating them in red to indicate contamination and in green when the surface is clean. Unlike traditional thermoluminescent dosimeters, the system offers real-time detection and locates all contaminating sources, avoiding spot instrumentation.

This reduces operator dependence and the risks of human errors. Additionally, the system detects contamination in large areas such as hot chambers and nuclear facilities without requiring lengthy and invasive cleaning procedures for the entire workspace, thereby increasing safety.

Possible Applications

  • Laboratory environments;
  • Environments that use radiation (medical radiotherapy facilities, airports, cargo, and container inspection areas);
  • Potentially contaminated environments.


  • Innovative, highly performing materials;
  • High comfort and low electrical risk exposure;
  • Shorter and less invasive environmental cleaning procedures as the contaminated areas are precisely known;
  • Practical and cost-effective system;
  • Capability to connect to mobile devices.
