90Sr in mammal teeth taken in the Semipalatinsk Test Site measured by imaging plates
ثبت نشده
چکیده
The concentrations of 9{)Sr in mammal teeth taken in north-west part of Semipalatinsk Test Site were measured by using imaging plates, The highest concentration detected in the present study was 13Bqig, being comparable with the values previously detected in cow teeth from South Ural region. It suggests that, at least locally, the soil in north-west part of the Test Site is possibly highly contaminated. It would be necessary to investigate the source of this high level of contamination, such as radiological weapon tests, before providing the land for agricultural use.

Nature of radioactive contamination in soils of the pine forest in the territory adjacent to Semipalatinsk test site
ABSTRACT Background: This work investigated radioactive contamination in soils of the pine forest in the territory adjacent to Semipalatinsk test site. Materials and Methods: Thirty samples from the soil were collected from six different a soil profile was laid out (research areas). Activity concentrations of 137Cs and 241Am were determined using a Canberra GX-2020 solid-state gamma-spectromet...
متن کاملHigh incidence of micronuclei in lymphocytes from residents of the area near the Semipalatinsk nuclear explosion test site.
The Semipalatinsk area is highly contaminated with radioactive fallout from 40 years of continuous nuclear testing. The biological effects on human health in this area have not been studied. Significant remaining radioactivities include long-lived radioisotopes of 238,239,400Pu, 137Cs and 90Sr. To evaluate the long-term biological effects of the radioactive fallout, the incidence of micronuclei...
متن کاملEstimation of Remnant Dentin Thickness under Proximal Caries Using Digital Bitewing Radiography: An In-Vitro Study
Objectives: In restorative dentistry, it is essential to estimate the amount of remnant tooth structure after caries removal to make the best treatment plan. The present study was aimed to determine whether there is a correlation between the real thickness of remnant dentin under carious lesion and the radiographical measurement from photostimulable phosphor plates (PSPs). Methods: a whole numb...
متن کاملStrontium-90 concentration measurements in human bones and teeth in Greece.
Strontium-90 concentration was measured in human bones and teeth collected in Greece during the period 1992-1996. One hundred and five bone samples, mainly cancellous bone, and 108 samples, taken from a total of 896 individual teeth were processed. Samples were classified according to the age and sex of the donors. Samples were chemically pre-treated according to a specially devised method to e...
متن کاملEpr Tooth Dosimetry of Snts Area Inhabitants.
The determination of external dose to teeth of inhabitants of settlements near the Semipalatinsk Nuclear Test Site (SNTS) was conducted using the EPR dosimetry technique to assess radiation doses associated with exposure to radioactive fallout from the test site. In this study, tooth doses have been reconstructed for 103 persons with all studied teeth having been formed before the first nuclear...
