Localization of intestinal bleeding using a miniature Geiger counter.
This study reports the practical problems involved in the use of a miniature Geiger counter to detect the site of bleeding into the intestine. The observations so far have been made in dogs but its possible application in man is proposed.
متن کاملTactile Geiger Counter for Ubiquitous Computing
Acknowledgements Firstly and most importantly I would like to thank Professor Stephen Brewster for guiding me through this dissertation, for all the advice, phones and resources he lent me and for giving me the opportunity to work on a project that nobody else has really done before. I would very much like to thank Andrew Crossan for regularly diagnosing and fixing my slightly fickle and temper...
متن کاملA Magnetically Enhanced Wireless Micro-geiger Counter
This paper reports a micromachined Geiger counter with integrated permanent magnets that enhance the RF transmission from the discharges initiated by incident beta particles. With the intent of wireless sensing within the ultra wideband (UWB) spectrum, the transmission in the 2.0-2.8 GHz frequency range is investigated. The device consists of a 1x2 cm micromachined glass/Si cavity sandwiched be...
متن کاملTemperature Effect and Its Elimination in Geiger - Muller Tube Counters
It has been found that in the usual form of the Geiger-Miiller tube counter the rate of counting is affected by changes of temperature. The rate of counting, at a fixed potential applied to the tube, decreases as the temperature is increased. This indicates an increase in the density of the gas in the counter. Since it is hermetically sealed this can only be caused by evaporation of volatile ma...
