The CALS Raster file format is a standard for the interchange of graphics data. It was developed by the United States Department of Defense (DoD) as part of the Continuous Acquisition and Life-cycle Support (CALS) initiative.
The effective dose is the risk of radiation averaged over the entire body. [4] Ionizing radiation is known to cause cancer in humans. [4] We know this from the Life Span Study, which followed survivors of the atomic bombing in Japan during World War 2. [5] [4] Over 100,000 individuals were followed for 50 years.
Effective dose is a dose quantity in the International Commission on Radiological Protection (ICRP) system of radiological protection. [1]It is the tissue-weighted sum of the equivalent doses in all specified tissues and organs of the human body and represents the stochastic health risk to the whole body, which is the probability of cancer induction and genetic effects, of low levels of ...
The next step was an updated CALS Table Model DTD and semantics. Both are now available from OASIS. [1] As implementations of the CALS Table Model were developed, a number of ambiguities and omissions were detected and reported to the EPC. The differences in interpretation had led to serious interoperability problems.
The energy-depth-dose profile is a curve starting with a surface dose, ascending to the maximum dose in a certain depth d m (usually normalized as 100% dose), then descends slowly through depths of 90% dose (d 90) and 80% dose (d 80), then falls off linearly and relatively sharply though depth of 50% dose (d 50).
Some materials continue to weaken through aging, as the remaining free radicals react. [15] The resistance of these polymers to radiation damage can be improved by grafting or copolymerizing aromatic groups, which enhance stability and decrease reactivity, and by adding antioxidants and nanomaterials, which act as free radical scavengers.

The ICRP recommends limiting artificial irradiation of the public to an average of 100 mrem (1 mSv) of effective dose per year, not including medical and occupational exposures. [10] For comparison, radiation levels inside the United States Capitol are 85 mrem/yr (0.85 mSv/yr), close to the regulatory limit, because of the uranium content of ...
