Book Description
For many decades, investigations of the behaviour and implications of radioactive contamination in the environment have focused on agricultural areas and food production. This was due to the erroneous assumption that the consequences of credible contaminating incidents would be restricted to rural areas. However, due to the Chernobyl accident, more than 250,000 persons were removed from their homes, demonstrating a great need for knowledge and instruments that could be applied to minimise the manifold adverse consequences of contamination in inhabited areas. Also, today the world is facing a number of new threats, including radiological terrorism, which would be likely to take place in a city, where most people would become directly affected. A recent report from the US Commission on the Prevention of Weapons of Mass Destruction Proliferation and Terrorism concludes that it is most likely that a large radiological, or even nuclear, terror attack on a major city somewhere in the world will occur before 2013. For the first time ever, the specific problems of airborne radioactive contamination in inhabited areas are treated in a holistically covering treatise, pinpointing factorial interdependencies and describing instruments for mitigation. The state-of-the-art knowledge is here explained in Airborne Radioactive Contamination in Inhabited Areas y leading scientists in the various disciplines of relevance. Unique holistic description of airborne radioactive contamination of inhabited areas and its consequences State-of-the-art information on problems associated with both accidental and malicious contamination events, in particularly 'dirty bombs' Detailed description of processes and parameters governing the severity of contaminating incidents Written by key experts in the world

Book Description
Current technologies for the detection of airborne radioactive contamination do not provide real-time capability. Most of these techniques are based on the capture of particulate matter in air onto filters which are then processed in the laboratory; thus, the turnaround time for detection of contamination can be many days. To address this shortcoming, an effort is underway to adapt LRAD (Long-Range-Alpha-Detection) technology for real-time monitoring of airborne releases of alpa-emitting radionuclides. Alpha decays in air create ionization that can be subsequently collected on electrodes, producing a current that is proportional to the amount of radioactive material present. Using external fans on a pipe containing LRAD detectors, controlled samples of ambient air can be continuously tested for the presence of radioactive contamination. Current prototypes include a two-chamber model. Sampled air is drawn through a particulate filter and then through the first chamber, which uses an electrostatic filter at its entrance to remove ambient ionization. At its exit, ionization that occurred due to the presence of radon is collected and recorded. The air then passes through a length of pipe to allow some decay of short-lived radon species. A second chamber identical to the first monitors the remaining activity. Further development is necessary on air samples without the use of particulate filtering, both to distinguish ionization that can pass through the initial electrostatic filter on otherwise inert particulate matter from that produced through the decay of radioactive material and to separate both of these from the radon contribution. The end product could provide a sensitive, cost-effective, real-time method of determining the presence of airborne radioactive contamination.
