Product Description

Specifications

Radiation detected:
Alpha above 7.5 MeV, Beta above 100 keV, and Gamma above 7 keV
Operating ranges:
0 to 5 mR/h or 0 to 50 µSv/h
0 to 50 mR/h or 0 to 500 µSv/h
0 to 500 mR/h or 0 to 5 mSv/h
0 to 5 R/h or 0 to 50 mSv/h
0 to 50 R/h or 0 to 500 mSv/h
Accuracy:
Within 10% of reading between 10% and 100% of full scale indication on any range, exclusive of energy response. Calibration source is 137Cs
Detector:
Chamber:
349 cc volume air ionization
Chamber wall:
246 mg/cm2 thick phenolic
Chamber window:
6.6 mg/cm2 Mylar, protected by steel mesh, 46 cm2 detection area
Beta slide:
440 mg/cm2
451B-DE-SI:
In order to achieve energy response consistent with measurements of H*(10) as required by ICR4-47, aluminum has been added to the back wall, 38% of the side wall area, and to the beta slide. With the Beta Shield open, the 451B can measure skin dose at 10* (0.07), and Deep Dose H* (10) with Beta shield closed.
Controls
ON/OFF and MODE
Automatic features
Auto-zeroing, auto-ranging, and auto-back
Response time:
0 to 5 mR/h (0 to 50 µSv/h) – 8 sec
0 to 50 mR/h (0 to 500 µSv/h) – 2.5 sec
0 to 500 mR/h (0 to 5 mSv/h) – 2 sec
0 to 5 R/h (0 to 50 mSv/h) – 2 sec
0 to 50 R/h (0 to 500 mSv/h) – 2 sec
Power requirements:
Two 9 V alkaline, 200 hours operation
Warm-up time:
One minute
Modes:
Integrate mode:
Operates continuously 30 seconds after the instrument has been turned on. Integration is performed even if the instrument is displaying in mR/h or R/h
Freeze mode:
Will place a tick mark on the bar graph display to hold on the peak displayed value. The unit will continue to read and display current radiation values
Display:
LCD analog/digital with backlight
Analog:
100 element bar graph 6.4 cm long. Bar graph is divided into 5 major segments, each labeled with the appropriate value for the range of the instrument
Digital:
2.5 digit display is followed by a significant zero digit depending on the operating range of the instrument. The units of measurement are indicated on the display at all times. Digits are 0.25 in (6.4 mm) high. Low battery and freeze indicators are also provided on the display
