Examples Of Beta Response; Fast Neutron Response (Pube); Figure 1-2: Nominal Photon Energy Response - Thermo Scientific RO-20 Operating Manual

In the following examples, the RO-20 had been calibrated to
slide facing the source.
• ±30% from 8 keV to 1.3 MeV, with the open slide facing the source.
• ±15% from 33 keV to 1.3 MeV, with the closed slide facing the source.
• ±15% from 55 keV to 1.3 MeV, through the side of the instrument.

Examples of Beta Response

•
Uranium slab: 30% of true mrad/h field behind 7 mg/cm
resting on the slab (slide open).
90 90
•
Sr– Y: Approximately 93% of true mrad/h field at 30 cm with slide open.

Fast Neutron Response (PuBe)

Reads approximately 8% in mR/h of true neutron field in mrem/h.
