X-ray dosimetry
Principle: The molecules of air within a plate capacitor are to be ionized by X-rays. The ion dose, ion dose rate and local ion dose rate are to be calculated from the ionization current and the radiated mass of air.
Tasks:
1. The ion current at maximum anode voltage is to be measured and graphically recorded as a function of the capacitor voltage by using two different beam limiting apertures.
2. The ion dose rate is to be determined from the saturation current values and the air masses penetrated by radiation are to be calculated.
3. The energy dose rate and various local ion dose rates are to be calculated.
4. Using the d = 5 mm aperture, the ion current is to be determined and graphically recorded at various anode currents but with maximum anode and capacitor voltages.
5. The saturation current is to be plotted as a function of the anode voltage.
6. Using the d = 5 mm aperture, the ion current is to be determined and graphically recorded at various anode currents but with maximum anode and capacitor voltages.
7. Using the two different diaphragm tubes and the fluorescent screen, the given distance between the aperture and the radiation source at maximum anode coltage and current is to be verified.
