Microprocessor based radiation monitor with extended possibilities

A microprocessor based instrument is presented. Convenient facilities for radiation monitoring are acquired by incorporated adequate software. The main requirements fulfilled by software are defined by the task of the radiation monitor, i.e. obtaining dose rate or count rate of pulses from detector. The choice of a convenient algorithm for count rate is discussed. There are other values that may be of interest in application of radiation monitor, such as error of shown results, tendency of dose rate changes, the warning signal of approching the alarm level and the signal of reaching the alarm level. Inclusion of all possibilities in the software support of the instrument is discussed and the accepted solution is described. (author)
