Abstract :
This paper compares and contrasts the use of MOSFET dosimeters and extended rem counters for neutron detection in cosmic radiation fields. These technologies have been exposed to a reference field and data are presented that demonstrate the contrasting sensitivities of these approaches. The MOSFETs are observed to be insensitive to dose levels associated with cosmic fields whilst the extended rem counters give a good response, demonstrating that copper has potential as a replacement for lead in these systems
