I have spend a huge amount of time this afternoon trying to get and exact latitude and longitude of this sink hole but it is my contention that the
seismos installed are NOT to monitor the sink-hole but to monitor the salt dome, over which they are installed.
Within a couple of seconds.
Oil and gas production and processing operations sometimes cause naturally occurring radioactive materials (NORM) to accumulate at elevated
concentrations in by-product waste streams
The EPA has the following information:
Much of the petroleum in the earth's crust was created at the site of ancients seas by the decay of sea life. As a result, petroleum deposits
often occur in aquifers containing brine (salt water). Radionuclides, along with other minerals that are dissolved in the brine, precipitate (separate
and settle) out forming various wastes at the surface:
mineral scales inside pipes
contaminated equipment or components
Because the extraction process concentrates the naturally occurring radionuclides and exposes them to the surface environment and human contact, these
wastes are classified as TENORM.
As you can see, there are several vectors in which these by products can be introduced into the environment.
The amounts present vary greatly:
Because radium levels in the soil and rocks vary greatly, so do their concentrations in scales and sludges. Radiation levels may vary from
background soil levels to as high as several hundred nanoCuries per gram.
While the low end of the scale is nominal and probably not even worth much consideration, the levels at the higher end are problematic.
These byproducts occur in many production sites, some in greater concentrations than others:
An estimated 30 percent of domestic oil and gas wells produce some TENORM (McA88). In surveys of production wells in 13 states, the percent
reporting high concentrations of radionuclides in the wells ranged from 90 percent in Mississippi to none or only a few in Colorado, South Dakota, and
Wyoming (McA88). However, 20 to 100 percent of the facilities in every state reported some TENORM in heater/treaters.
Nothing is said about the Louisiana levels of these byproducts, CanjuBoy may be able to locate this information as he is local to the area.
What problems do these materials represent?
Because of concerns that some pipes may have contaminated the surrounding environment, radiological surveys were conducted by EPA's Eastern
Environmental Radiation Facility. These surveys showed that some equipment and disposal locations exhibited external radiation levels above 2 mR/hr
and radium-226 soil contamination above 1,000 pCi/g. Some contamination had also washed into a nearby pond and drainage ditch at one site, as well as
into an agricultural field with subsequent uptake of radium by vegetation.
As is the case in many industries, the contamination of the environment is at greater risk levels from past production as the dangers were not
sufficiently accounted for.
The problem s not external exposure, but rather the possibility that these materials may be introduced into the environment and taken up by various
Radiation exposure is subject to the inverse Square Law:
As one of the fields which obey the general inverse square law, a point radiation source can be characterized by the relationship below whether
you are talking about Roentgens , rads, or rems . All measures of exposure will drop off by inverse square law
The thing that makes internal exposure a concern is that the law works in both directions so that any internally lodged particle will be in direct
contact with living tissue, resulting in maximum damage.
Different isotopes are chemically similar to other minerals that the body uses in it's normal biological processes. Strontium, for example is similar
to calcium and will lodge within bone, elevating the risk of bone cancer and leukemia.
