Scintillation Probes:
- PAS-8 Alpha Scintillation Probe with 1-3/4''
diameter x 0.8 mg/cm2 window. For use wherever a high efficiency,
low background alpha detector is indicated. (Figure
1)
- PAS-9 Alpha Scintillation Probe with a
4-1/2'' diameter x 0.8 mg/cm2 window. The 100 cm2 face
of this probe allows rapid surveys to be made of personnel, equipment
or flat surfaces. Background is in the order of several counts per
hour. Sensitivity is 10 to 20% for 5 MeV. alphas based on 4Pi
geometry (20 to 40% based on 2Pi geometry). The protective grid
is physically separated from the window thus making contamination
of the window extremely unlikely. Grid may be removed for cleaning
without disturbing the window. some sacrifice of sensitivity has been
make for this feature. (Figure 2)
- PAS-9R Similar to PAS-9,
Sensitivity Area: 125cm2.
Net Open: 100cm2.
Rectangular FACE: 5.5'' x 4'' Gross. (Figure 3)
- PBS-42 Identical to the PBS-44
except that the sensitive diameter is 1.5''. (Figure
2)
- PBS-43 Beta Scintillation probe. 0.020''
Phosphor organic. 3.75'' diameter gives a 45 cm2 sensitive
area. (Figure 2)
- PBS-44 Beta Scintillator for rapid monitoring
of large surfaces as well as for measuring activity on filter paper
in high volume air samplers. Sensitive diameter is 100 cm2.
Detects betas with energies greater than .05 MeV. The window is normally
protected by a 79% open grid. Optionally, a cap is furnished to exclude
all betas of 2.5 MeV or less.
- PBS-44R Similar to PBS-44,
Sensitivity Area: 125cm2.
Net Open: 100cm2.
Rectangular FACE: 5.5'' x 4'' Gross. (Figure 3)
- PABS-42 Alpha plus Beta Scintillation
Probe, ZnS(Ag) Alpha Phosphor laminated onto 0.010'' Phosphor organic
Beta Scintillator. 15 cm2 sensitive area probe has 2'' outside
diameter. (Figure 2)
- PABS-47 Alpha plus Beta Scintillation
Probe, ZnS(Ag) Alpha Phosphor laminated onto 0.010'' Phosphor organic
Beta Scintillator. 0.010'' Phosphor organic. 100 cm2 sensitive
area. (Figure 2)
