The Application of Gamma Spectrometric Techniques with Plastic Scintillators for the Suppression of “Innocent Alarms” in Border Monitoring for Nuclear and other Radioactive Materials

Border monitoring equipment for nuclear and other radioactive materials apply fixed installed, automated “portal monitors” at checkpoints such as road and rail border crossings, airports or seaports, to detect gamma and neutron radiation in order to alert the front line officer about the presence of nuclear and other radioactive materials. Although highly sensitive and reliable systems are avai...

Development of RadRob15, A Robot for Detecting Radioactive Contamination in Nuclear Medicine Departments

Accidental or intentional release of radioactive materials into the living or working environment may cause radioactive contamination. In nuclear medicine departments, radioactive contamination is usually due to radionuclides which emit high energy gamma photons and particles. These radionuclides have a broad range of energies and penetration capabilities. Rapid detection of radioactive contami...

Remote detection of radioactive material using high-power pulsed electromagnetic radiation

Remote detection of radioactive materials is impossible when the measurement location is far from the radioactive source such that the leakage of high-energy photons or electrons from the source cannot be measured. Current technologies are less effective in this respect because they only allow the detection at distances to which the high-energy photons or electrons can reach the detector. Here ...

Statistical Approach to Radioactive Target Detection and Location via Wireless Sensor Networks

—The detection of materials or devices for nuclear or radiological weapons of mass destruction is fundamentally important to national safety and security, and detection technologies are necessary both to nd and to verify the location of those materials or devices. To ful ll this task, this paper presents a statistical approach to the detection and location of radioactive target via wireless sen...

Active Remote Detection of Radioactivity Based on Electromagnetic Signatures

This paper presents a new concept for the remote detection of radioactive materials. The concept is based on the detection of electromagnetic signatures in the vicinity of radioactive material and can enable stand-off detection at distances greater than 100 m. Radioactive materials emit gamma rays which ionize the surrounding air. The ionized electrons rapidly attach to oxygen molecules forming...
