Resumen
In high-intensity, mixed and pulsed neutron fields the use of
spectrometers or area monitors with ac ve detectors is useless; in these
condi ons neutron measuring devices must have a passive detector. Here a
passive neutron area monitor with CR39 track detector was designed and the
response was calculated. Materials and Methods: The response of a passive
neutron area monitor with CR39 track detector has been calculated with the
MCNPX code. To increase the detec on efficiency a 10B converter was
included. The response was calculated using 47 monoenerge c neutron
sources. Results: A passive neutron area monitor using a CR39 with 10B
converter was designed where fluence and H*(10) responses were calculated.
Conclusion: The shape of the responses is similar to responses reported for
neutron monitors with ac ve detectors.
