| Popis: | The cylindrical NE2575 and spherical PTW32002 chamber types were tested in this paper to determine their performance at different source-chamber distances, field sizes and two radiation qualities. To ensure an accurate measurement, there is a need to apply a correction factor to NE2575 measurements at different distances because of differences found between the reference point defined by the manufacturer and the effective point of measurements. This correction factor for NE2575 secondary standard from the Center for Radiation Protection and Hygiene of Cuba was assessed with a 0.3% uncertainty using the results of three methods. Those laboratories that use the NE2575 chambers should take into consideration the performance characteristics tested in this paper to obtain accurate measurements. |
