PURPOSE To determine the effect on machine output calibration, following the TG-51 protocol, as the water temperature increasingly deviates from Standard temperature (22°C) METHODS: A water tank was set up according to TG-51 protocol. Two sets of measurements were taken and the pressure recorded. The measurements consisted of readings at different temperatures. In the first set, P(ion), P(pol),...
Since 1984, the Radiological Physics Center (RPC) has used the American Association of Physicists in Medicine Task Group 21 (TG-21) protocol (absorbed dose determination) as the basis of its On-site Dosimetry Review visits to institutions participating in the National Cancer Institute's cooperative clinical trials. Subsequent to the TG-21 protocol, the Task Group 25 (TG-25) report on electron-b...
We introduce TG/MC, a Monte-Carlo approach for evaluating the impact of uncertainty about vulnerabilities upon forecasts of security for a real-world system modeled by a protection graph. A TG/MC model defines a vulnerability as a potential change to an otherwise safe initial protection graph that, if exploited, leads to an unauthorized state, a violation of the system’s security policy through...
