Ro-20 RB-XXX-XXXXXX E 1-3
Löw 08.10.2008
In the following examples, the RO-20 had been calibrated to
137
Cs (slide closed), with the
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.
1.3.8 Examples of Beta Response
•
Uranium slab: 30% of true mrad/h field behind 7 mg/cm
2
window, with the RO-20
resting on the slab (slide open).
• 90
Sr–
90
Y: Approximately 93% of true mrad/h field at 30 cm with slide open.
1.3.9 Fast Neutron Response (PuBe)
Reads approximately 8% in mR/h of true neutron field in mrem/h.
