A common gamma-ray log records the total radiation and cannot distinguish between the radioactive elements, while a spectral gamma ray log (see below) can. For standard gamma-ray logs, the measured value of gamma-ray radiation is calculated from concentration of uranium in ppm, thorium in ppm, and potassium in weight percent: e.g., GR API = 8 ...
Thus the presence or absence of gamma rays in a borehole is an indication of the amount of shale or clay in the surrounding formation. The gamma ray log is useful in holes drilled with air or with oil based muds, as these wells have no SP voltage. Even in water-based muds, the gamma ray and SP logs are often run together.
The formation evaluation gamma ray log is a record of the variation with depth of the natural radioactivity of earth materials in a wellbore. Measurement of natural emission of gamma rays in oil and gas wells are useful because shales and sandstones typically have different gamma ray levels.
The Spiller Farm Paleoindian Site, designated Site 4.13 by the Maine Archaeological Survey, is a prehistoric archaeological site in Wells, Maine.Located overlooking a stream on the Spiller Farm property on Branch Road, it is an extensive site at which a fine collection of stone artifacts has been found, dating to c. 8,000 BCE.
In 2004 H.E.S.S. was the first IACT experiment to spatially resolve a source of cosmic gamma rays. In 2005, it was announced that H.E.S.S. had detected eight new high-energy gamma ray sources, doubling the known number of such sources. As of 2014, more than 90 sources of teraelectronvolt gamma rays were discovered by H.E.S.S. [2]
A developer is proposing to build more than 100 new homes and about 40 new townhouses on currently wooded property behind the antiques shop at 502 Post Road in Wells, Maine.
