An improved radiation detection device measures a broad range of dose rate levels. According to one arrangement, the radiation detection device calculates a radiation value based on, gamma count information representing counts for different energy levels of radiation in a radiation field as well as a radiation intensity indicator value (e.g., photomultiplier tube anode DC current, measured directly by conventional Analog to Digital Converters or indirectly by power or current consumption information indicating how much energy is required to maintain a photomultiplier tube at a constant voltage) that is at least proportional to an amount of overall radiation energy detected in the radiation sample. Based on a combination of the gamma count information and the radiation intensity indicator value, a controller associated with a corresponding radiation detection device can calculate a radiation dose rate associated with the received radiation sample.
