The radiometric survey is our key technology. We are using scintillation counters for measuring gamma radiation emanating from the Earth because it provides valuable information about elements and structures of the underground. We detect sub-surface resources of water bodies, oil prospects, kimberlite pipes and potentially gold and other metals, by using both the background radiation and spectrographic analysis of specific isotopes.
How scintillation counters work
- Gamma radiation is analyzed by sensitive scintillation counters with specially dotted crystal sensors in glide mode.
- Through these crystal sensors, gamma rays are received, converted into light flashes, and amplified as electric impulses by a photo multiplier.
- The data is recorded in impulses per second (ips).
- Scintillation counters are commonly used in geophysical surveys for several decades. However, most of them are employed for analyzing radioactive spots.
- On the other hand, using background radiation for surveys is not common knowledge. This is our USP.
How we use our scintillation counters
The specific scintillation counters that we are using provide quantitative and qualitative results, making possible a large number of geophysical analyses, i.e.:
- Identifying the exact location of groundwater deposits and aquifers, as well as potential sources of primary water
- Deposits of minerals and precious metals
- Search for petroleum prospects
- Detection of kimberlite pipes
- Anomalies such as faults, fissures, tectonic distortions
Dr. Armin Bickel was a member of the NASA team of Wernher von Braun, the father of the Apollo program that sent man to the moon. After his retirement, Dr. Bickel developed portable scintillation counters with very high accuracy. Both von Braun and Dr. Bickel emigrated from Germany to the US after WW II.
Dr. Bickel was an endowed researcher and had a wide knowledge spectrum, most of which is not available anymore today.
However, Dr. Bickel introduced Edgar Gummerum to the “secrets” of his proprietary method of interpretation of scintillation counter signals.
