This is a word of caution to anyone using ionization chambers protected by thin rubber sheaths in water. Four Farmer-type ionization chambers contaminated with talcum powder were received for calibration by the Accredited Dosimetry Calibration Laboratory at the University of Texas M. D. Anderson Cancer Center. The chambers show a marked energy dependence (5% to 20%) to soft orthovoltage x rays....
International cooperation is an integral part of furthering medical and scientific progress. Many specilist societies exist for that purpose and have written into their constitutions that such cooperation and coordination is their aim. They hope to achieve their aims by exchange, in all languages, of information and by so doing strengthen the relations between individual physicians and scentist...
We present recent results of an extensive aging test, performed at the CERN Gamma Irradiation Facility, on two bakelite Resistive Plate Chambers (RPC) detectors. With a method based on a model describing the behavior of an RPC exposed to a large particle flux, we have periodically measured the electrode resistivity r of the two detectors over 3 years. We observed a large increase of r with time...
