Operators Manual
1-6
Resolving time: 1 microsecond
Plateau Slope: 2% per 100 V
Tube Life expectancy: >10 10 counts
Neutron Sensitivity: 2000 counts/mRem (nominal)
The neutron Energy Response is as follows:
The energy range is thermal 0.025 eV to 15 MeV. The accuracy is within 10% of the theoretical ICRP
dose rate.
The directionality effect is less than +/- 20% in 3 orthogonal directions.
The standard ranges and engineering units available are:
Rate: 1 μRem/hr to 75 Rem/hr 0 μSv/hr to .75 Sv/hr
0 μRad/hr to 9 Rad/hr 0 μGy/hr to .09 Gy/hr
0 CPM to 2.5 x 106 CPM
0 CPS to 41,660 CPS
Integrate:
0 μRem to 1000 Rem 0 μSv to 10 Sv
0 μRad to 125 Rad 0 μGy to 1.25 Gy
0 to 10 9 Counts 0 to 10 9 Counts
The tube is insensitive to gamma rays and shows no response in l37 Cs gamma radiation in fields up to
500 mR/hr.
The overall dimensions of the assembly are: 12.50 in diameter and overall length of 10.25 in. The
assembly comes with two mounting brackets. The total weight of the assembly is 21 lbs.
The detector assembly operating range is -80°C to +80°C
The detector can be placed up to 10 ft (3 m) away from the Model 1060.
1.3.3 Photomultiplier Tubes/Scintillators
The standard scintillator is a Nal(T1) crystal on a photomultiplier tube. There are two standard detectors
configurations, however, many others models are available. Please see the Model 943 series detectors.
P/N Detects Nominal HV Max Dist
1060-XXX X-rays, gamma rays 750-1100 10 feet
943-36 X-rays, gamma rays 750-1100 1500 feet
Nominally, the calibration would set the high voltage to provide pulse heights of 2mV/keV.
