Alarm inhalation dosemeter for long livingradioactive dust due to an uncontrolled release

摘要

MyRIAM is the acronym for My Radioactivity In Air Monitor and points out thatthe device was designed for personal use to detect any radioactivity in the air at theplace and at the moment of danger. The active air sampling process enables a detection limitseveral orders of magnitude below that of Gamma detectors. Therefore, it is the unique way todetect dangerous exposures in time.Individual protection against inhalation of long living radioactive dust (LLRD) saves human lifeand health. LLRD may occur in natural environment as well as in case of nuclear accidence ormilitary and terrorist attacks. But in any case, the immediate warning of the population is of greatimportance. Keep in mind: it is very easy to avoid LLRD inhalation - but you have to recognizethe imminent danger. The second requirement of gap-less documentation and reliable assessmentof any derived LLRD exposure is building the link to Dosimetry applications.The paper demonstrates the possibility to design small and low cost air samplers, which can beused as personal alarm dosimeters and fulfil the requirements mentioned above.Several test measurements taken by a mobile phone sized MyRIAM, shall be used to demonstratethe correctness of this statement.
