Alpha-Radioactive Isotopes Monitoring of Human Body Contamination by Trace of Air Ions Presence

AbstractThe new device described in this report provides the reliable fast detection of alpha-particles at a distance from the radiation source significantly longer than the alpha-particle run in air by measuring the ions clusters, produced by alpha decay in the air. That physical factgives possibility to developportal monitor alpha-radioactive contamination control with absence of limitations associated with irregular configuration of surfaces; fast examination of any objects, materials addition to the human body. Design of the portal monitor for human body alpha-radioactive contamination control may use for safety inspection nuclear plants employers or in case of radiation terroristic danger is presented
