Gaining information about an unknown gas source is a task of great importance with
applications in several areas, including responding to gas leaks or suspicious smells …

Anomalous radiation source detection in urban environments is challenging due to the
complex nature of background radiation. When a suspicious area is determined, a radiation …

Hazardous materials (HAZMAT) released into the atmosphere pose both an immediate and
chronic risk to human health. Characteristic examples include the Sarin gas terrorist attacks …

Finding sources of airborne chemicals with mobile sensing systems finds applications
across the security, safety, domestic, medical, and environmental domains. In this paper, we …

In this paper, we propose a path planning method for the localization of radiation sources
using a mobile robot equipped with an imaging gamma-ray detector, which has a field of …

Based on the convolutional neural network (CNN), a novel technique is investigated for lost
gamma source detection in a room. The CNN is trained with the result of a GEANT4 …

Autonomous radiation source detection has long been studied for radiation emergencies.
Compared to conventional data-driven or path planning methods, deep reinforcement …
