Sentence examples for distribution of radioactive from inspiring English sources
Experts were not surprised that high cesium levels were recorded at one spot in Japan; the distribution of radioactive particles from the plant depends on wind and precipitation: even a brief shower can literally rain fallout onto one spot.
In any QC procedure, radioactive phantoms are needed that contain a certain distribution of radioactive material such that specific performance properties of the scanner can be monitored.
The Compton camera is a viable and convenient tool used to visualize the distribution of radioactive isotopes that emit gamma rays.
Most radiopharmaceuticals emit gamma rays, and therefore the distribution of radioactive tracer can be measured with a gamma camera or positron emission tomography (PET) scanner.
Compartmental analysis initially developed from studies of the uptake and distribution of radioactive tracers, but today it plays a fundamental role in many parts of medicine, bioengineering and environmental science [20 22].
Two modes of internal heating by radioactive sources are considered: uniform distribution of radioactive elements within undifferentiated bodies and heating of the icy mantle by heat flux from the rocky core.
It resolves either two-dimensional (2D) or three-dimensional (3D) distributions of radioactive sources in applications for homeland security, environmental monitoring, radiation contamination monitoring, baggage inspection, nuclear power plant monitoring, and more.
As an advanced imaging technique, position emission tomography (PET) allows noninvasive detection and quantitative assay of the in vivo distribution profile of radioactive isotope-labeled probes and has been extensively used in the diagnosis and staging of various diseases [ 1, 2].
Beyond the radiation monitoring, Proehl says that scientists will need to map the distribution of different radioactive species in the environment.
The direction of transport and the downwind distribution of the radioactive fallout depend on the wind velocity and direction while the degree of dispersion depends on atmospheric stratification, turbulence, etc.
Random and systematic factors such as the Poisson distribution of the radioactive decay and noise in addition to the processing parameters used to generate the images [1 6] can contribute to image heterogeneity as well as variations in uptake due to the non-homogenous features of the tissues being analysed (e.g. [7 11]).
