Specification
AT140 Neutron Calibration Facility | |
Source of neutrons, peak neutron flux | 238Pu-Be: 5∙107 neutron/s 252Cf: 5∙108 neutron/s |
Fast neutron flux density | 2.5 – 3.5∙103 neutron/(s∙cm2) |
Slow neutron flux density | 1 – 1.4∙103 neutron/(s∙cm2) |
Ambient and personal dose equivalent rates | 3.5 – 4.0∙103 µSv/h |
Intrinsic relative error | ±5% for neutron flux density ±7% for ambient and personal dose equivalent rates |
Actual values of range limits and errors are determined by calibration |
