Abstract： |
The invention discloses an eliminating method of error in omission of dosage equivalent meter around neutron in the pulse neutron radiation field or strong neutron radiation field applying technical domain, which is characterized by the following: utilizing charge quantity output by BF3 proportional pipe to be direct ratio to energy loss of electric particle in the pipe to test over two neutrons; increasing the output pulse amplitude; connecting multiple discriminators at the back of the equivalent meter to correspond to overlapped threshold of one, two and three neutrons; transmitting the output pulse of different discriminators into microprocessor; calculating the real dosage equivalent according to the probability of the overlapped energy spectrum; correcting the omission number. The invention is easy to process data with simple structure, which can correct the omission number effectively. |
