The Thermo Scientific™ NRD 9 in. Neutron Ball is an REM (Roentgen Equivalent Man) detector that uses a moderated He-3 tube supplying neutron sensitivity and gamma rejection. It measures neutron dose rate, capturing thermal neutrons and fast neutrons.
The Thermo Scientific™ NRD 9 in. Neutron Ball is a REM (Roentgen Equivalent Man) detector that uses a moderated He-3 tube supplying neutron sensitivity and gamma rejection. It measures neutron dose rate for thermal neutrons and fast neutrons.
- High sensitivity and excellent gamma rejection engendered by properties of He-3
- Calibrated for ambient dose rate equivalent H*(10)
- Optional wall mounting bracket available
Recommended for: Neutron monitoring
