Abstract:
A method for detecting and suppressing extraneous radiation influences in radiometric measurements in which measurements are performed over a useable pulse amplitude spectrum, comprising:defining a measurement channel (MK) that extends at least essentially over the entire usable pulse amplitude spectrum of radiation pulses having a first pulse rate; defining at least one substitute channel (EK) that encompasses only a fraction of the usable pulse amplitude spectrum of radiation pulses having a second pulse rate; calibrating the measurement channel (MK) and substitute channel (EK) in terms of identical variables; defining a relation between measurement values, defined by the respective pulse rates of the measurement channel (MK) and substitute channel (EK) such that a substantial variation from a nominal value occurs in the value of the relation when extraneous radiation is detected; and performing a radiometric measurement and determining the value of the relation for the measurement values obtained during the measurement so as to detect and suppress extraneous radiation influences.
