Patent number: 7737401Abstract: 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.Type: GrantFiled: June 19, 2007Date of Patent: June 15, 2010Assignee: Thermo Fisher Scientific Inc.Inventors: Michael Iwatschenko-Borho, Norbert Trost, Ralf Pijahn

Patent number: 7456405Abstract: A radiation measuring instrument implements an energy ratio technique that utilizes a ratio between a measured radiation count rate and a detected radiation dose rate to determine if an alarm should be signalled to an operator of the device of this invention. The radiation measuring instrument uses an “inorganic” scintillation or radiation detection material, such as a Thallium doped sodium iodide (NaI(TI)) material, which operates in relatively compact or small sizes to detect radiation. The radiation measuring instrument also uses a ratio of two measured parameters to detect gamma radiation from artificial (hidden) radioactive material where the parameters include (i.) a total number of counted or detected gamma particles and (ii.) a measured, detected, or otherwise derived gamma dose rate.Type: GrantFiled: March 8, 2005Date of Patent: November 25, 2008Assignee: Thermo Fisher Scientific Inc.Inventors: Michael Iwatschenko-Borho, Norbert Trost, Ralf Pijahn
