Introduction
he Ludlum Model 4404-16 Geo-Exploration System provides
radiation surface measurements to help discern the underlying
geology. It utilizes a large scintillation detector, the Ludlum Model
4404-16 multichannel electronics, a waterproof enclosure, and a
ruggedized laptop with integrated GPS (Global Positioning System). The
software will display the radiation data just like a chart recorder and log the
radiation data and GPS coordinates into a comma delimited file. The “KML
Generator” software program converts the data files into files suitable from
viewing in Google Earth or any other 3D earth
browser implementing the KML (Keyhole
Markup Language) encoding.
Subsurface oil and gas fields have been mapped
using surface radiation sensors since the 1950s.
Radiation “anomalies” are created over such
fields due to the vertical migration of
hydrocarbons. While such readings may suggest
or confirm the presence of underground fields,
it is important to realize the limitations of these
readings. It is not possible to tell either the
depth or the ultimate productivity of a well or
field. These radiation anomalies are not present
over lakes or flooded areas. Ludlum
Measurements cannot guarantee any
conclusions or results based on the information
provided by this system.
The Ludlum Model 4404-16 has additional uses.
It may be used for radioactive ore prospecting.
The settings may be customized for uranium or
other radioactive isotopes. It may also be used
for general radiation survey for radioactive
contamination.
