        Additional work by EPA and individual states included a comprehensive health effects study related to the use of slag from elemental phosphorus plants for paving purposes in Idaho; an assessment of the phosphate mining industry in Florida, including an evaluation of guidelines for homes built on reclaimed mining lands; and complete radiation. Uranium mining in Arizona has taken place since Prior to the uranium boom of the late s, uranium in Arizona was a byproduct of vanadium mining of the mineral carnotite.. California. Uranium was discovered in in the Sierra Nevada of Kern County, along the Kern River about 30 miles (50 km) northeast of mines, the Kergon mine and the Miracle mine, made small.

      Calculation of Airborne Radioactivity Hazard From Machining Volume-Activated Materials Page 2 and imposing delays prior to enclosure access allow for decay of these nuclides and essentially eliminate the airborne radioactivity hazard to the environment and workers.   Central Florida Homeowners Sue The Mosaic Company over Radiation Health Risks from Phosphate Mining Lawsuit charges mining giant, real estate developers failed to warn homeowners about contamination.

      In , million metric tons of marketable phosphate rock, or phosphorite, was mined in the United States, making the US the world's third-largest producer, after China and phosphate mining industry employed 2, people. The value of phosphate rock mined was US$ billion.. As of , there are 10 active phosphate mines in four states: Florida, North Carolina, Idaho, and Utah. Some phosphate rock deposits, such as Mulberry in Florida, are notable for their inclusion of significant quantities of radioactive uranium isotopes. This syndrome is noteworthy because radioactivity can be released into surface waters [12] in the process of application of the resultant phosphate fertilizer (e.g. in many tobacco farming.

Genre/Form: Online resources: Additional Physical Format: Print version: Moxham, Robert Morgan, Airborne radioactivity surveys for phosphate in Florida.

Airborne radioactivity surveys totalling 5, traverse miles were made in ten areas in Florida, which were thought to be geologically favorable for the occurrence of uraniferous phosphate deposits. Abnormal radioactivity was recorded in eight of the ten areas surveyed.

The anomalies are located in Bradford, Clay, Columbia, DeSoto, Dixie, Lake, Marion, Orange, Sumter, Taylor, and Union Counties. Airborne radioactivity surveys totaling 5, traverse miles were made in 10 areas in Florida, which were thought to be geologically favorable for deposits of uraniferous phosphate.

Abnormal radioactivity was recorded in 8 of the 10 areas surveyed. The anomalies are located in Bradford, Clay, Columbia, DeSoto, Dixie, Lake, Marion, Orange, Sumter, Taylor, and Union Counties.

The phosphogypsum and rock phosphate samples were analysed for the estimation of radioactivity in them along with the soil samples. The results for activity concentration of U, Ra, Th and 40 K in the samples were compared with other studies carried out worldwide.

Table 2 shows the wide variation of activity concentrations of all the radionuclides observed by a number of. These efforts take advantage of the genetic association of uranium with apatite, which forms with phosphate deposits. The Airborne radioactivity surveys for phosphate in Florida.

| Adlibris. The phosphate deposits of Florida contain concentrations of these elements at levels about 30 to 60 times greater than those found in average soil and rock. Since Florida supplies approximately one-third of the world's phosphate, used in agricultural fertilizers, the state is concerned about the radon gas and radon progeny, or daughters.

Radiation and Your Environment: A Guide to Low-Level Radiation for Citizens of Florida. This is a public information booklet available at the FIPR library. Introduction. The Florida Institute of Phosphate Research (FIPR) was created in by the Florida Legislature (ChapterFlorida Statutes) and empowered to conduct research.

Introduction. CPAMs use a pump to draw air through a filter medium to collect airborne particulate matter that carries very small particles of radioactive material; the air itself is not radioactive. The particulate radioactive material might be natural, e.g., radon decay products ("progeny", e.g., Pb), or manmade, usually fission or activation products (e.g., Cs), or a combination of.

Inthe EPA's Florida Phosphate Initiative noted that some homes had median radiation concentration 4 to 22 times higher than pre-mined land and gamma exposure 2 to 3 times higher than normal.

Airborne radioactivity area. As defined in Ti Sectionof the Code of Federal Regulations (10 CFR ), the airborne radioactivity area is a room, enclosure, or area in which airborne radioactive materials, composed wholly or partially of licensed material, exist in concentrations that (1) exceed the derived air concentration limits (DACs), or (2) would result in an.

SourcesThere are two sources of radioactive contamination in drinking water. The first is naturally occurring radionuclides contained in the soil that water moves through. Some areas in Florida are susceptible to contamination from phosphate-rich soils and rock.

The second source of radioactive contamination comes from man-made sources. There is no known man-made contamination.Geological Survey of Finland, Special Pa –, 5 figures. Airborne radiometric data registered at low altitudes are used for detecting the presence of potassium, uranium and thorium in the field.
