PURPOSE This study examined the internal Cs exposure of residents and the Cs present in food products produced in Namie. Whole-body counter (WBC) was used for the measurement of internal exposure per each whole body of examinees. METHODS The food products which appeared to be used for consumption, were brought by residents and commercially available food items were excluded. Most of them were...

Introduction In the present nuclear age, the devastating effects of radioactivity have been highlighted by such issues as nuclear weapons testing and radioactive waste disposal, and by the reactor incidents at Three Mile Island and Chernobyl. These events illustrate the vexing problems that can be associated with high levels of radioactivity. However, the presence of radioactivity is not limite...

UNLABELLED Several groups have developed high-resolution PET systems and shown the feasibility of in vivo studies on small laboratory animals. In this investigation, one of these systems was validated for the performance of receptor imaging studies. For this, the radiotracer concentrations obtained in the same animals with PET and with autoradiography were quantified, and the correspondence bet...

Previous reports that radioactivity was bound to rat liver DNA in vivo after administration of 2-acetylaminofluorene (AAF)-9-14C were confirmed. In addition, administration of several other AAF derivatives, namely N-hydroxy-AAF-9 -14C, N-acetoxy-AAF-914C, and the glucuronide of N-hydroxyAAF-9)4C, led to the binding of higher levels of radioactivity to rat liver ribosomal RNA and DNA. Maximum le...

A mobile γ–ray spectrometer ( AMESOS ) has been developed using a 3”×3” NaI(Tl) detector, custom–made mounting holder, and portable electronics to perform in situ measurements of radioactivity. The was calibrated standard point sources its absolute efficiency determined. As field test operation, deployed on the premises University Athens Zografou campus focusing estimating NORM levels. Data wer...
