Evaluate variations in the internal doses of inorganic arsenic in terms of the various well contamination levels, the external dose
, and other potential sources of arsenic (primarily diet).
It has 75mm burrs to ensure proper grinding with higher volumes, a dispenser and on demand, an external dose
volume and control counter for dose numbers and a new system that uses special "shock absorbers" to reduce noise.
The authors claim their results suggest an increased risk of cancer among children exposed to external dose
rates of background ionizing radiation of [greater than or equal to] 200 nSv/h (1.
Assessment of external dose
from the measured radioactivity in soil samples collected from the Islamabad capital territory, Pakistan.
Elevated indoor external dose
rates may arise from high radionuclide content in building materials (Chen and Lin, 1996; Stoulos et al.
However building exposure geometry varies according to building design and material used, hence there are no adopted standard indoor external dose
The most critical unknown in the Techa river dose reconstruction data is the external dose
Suppose that data are available on an apical response X as a function of blood serum concentration C of a toxin rather than the external dose
Meeting these new challenges requires a public health approach (Goldstein 1995), including an enhanced scientific capability to measure exposure in the target human or ecosystem rather than at the end of the pipe, a better understanding of the relation between external dose
and target organ toxicity, and translation of advances in analytical chemistry and molecular biology to develop better biological indicators of exposure, effect, and susceptibility.
We classified all the municipalities on the basis of external dose
rate to form population fifths with roughly similar population sizes.
For those 44 workers never monitored for external radiation exposure, we assumed an external dose
of 0 mSv.
Such studies would reveal in detail the typical routes taken by the evacuees, as well as their speed, stops, and other aspects of their movement, and could greatly help in the reconstruction of early internal and external doses
for the population as a whole.
