Consists of two Alpha Spectra crystal packs each
consisting of four 256 cu. in. (total of 2032 cu. in.) downward looking crystals and one 256 cu.
in. upwards looking crystal, in conjunction with the digital GRS 256/12
channel Gamma Ray Spectrometer by PicoEnvirotec Inc. The system utilizes
individual signal processing from each crystal which provides a
significant improvement in the instrumentation, data processing and
interpretation. The enhanced capabilities over previous systems enables
the acquisition of more reliable and high spectral resolutions that,
when combined with the improved processing technology, provides new
dimensions in the presentation and interpretation of airborne gamma ray
surveys. Its features include:
-
Zero dead time and pulse pile up
-
Real time spectra non-linearity corrections
-
Automatic gain control and spectrum
stabilization on each PMT / crystal
-
Dual 256/512 multichannel analyzer
-
Distributed acquisition of detector signal with
and internal 1024 bit resolution
-
User defined detector volume of up to 18
crystals

The
Vertical Magnetic Gradient image shows alternating magnetic
horizons within the basement rocks along the western edge of the
survey block and relatively quiet magnetic sedimentary rocks to
the east; these sediments overlie the basement rocks and have a
shallow dip to the northeast. Within the sedimentary suite, the
Total Count image shows well defined radioactive horizons as
successively higher strata are exposed in a northeasterly
direction. The Uranium image further identifies which of these
are uraniferous. |
