Tissue Weighting Factor Definition
Tissue Weighting Factor Definition. A modern backscatter unit showing a passenger being screened. Tissue weighting factors according to icrp 103 (icrp 2007) tissue:
Weighting factor, wt, for an organ or tissue (t) is the proportion of the risk of stochastic effects resulting from irradiation of that organ or tissue to the total risk of stochastic effects when the whole body is irradiated uniformly. There are four basic tissues in the body: Measure of a radiation effect to be indicated more precisely.
Modelled Organ Equivalent Doses From Backscatter Scanners.
It represents a measure of the risk of stochastic effects that might result from exposure of that specific tissue. In radiation protection, the radiation weighting factor is a dimensionless factor used to determine the equivalent dose from the absorbed dose averaged over a tissue or organ and is based on the type of radiation absorbed. The most recent, overall recommendations of international commission on radiological protection (icrp) 103 (2007) include a tissue weighting factor of 0.12 for the entire remainder, and the remainder consists of 14 tissues:
Tissue Factor Tissue Factor (Tf) Is A Transmembrane Protein Found On The Surface Of Many Extravascular Cells, Including Vascular Smooth Muscle Cells And Adventitial Cells, Which Form Integral Part Of The Blood Vessel Wall.
An aggregation of similar cells or types of cells, together with any associated intercellular materials, adapted to perform one or more specific functions. As time goes on and data about our bodies sensitivity become more accurate, the values. Other factors including gender, age and individual sensitivity will influence the individual risk but such biological
Weighting Factor (Wt) Multipliers Of The Equivalent Dose To An Organ Or Tissue Used For Radiation Protection Purposes To Account For Different Sensitivities Of Different Organs And Tissues To The Induction Of Stochastic Effects Of.
The tissue weighting factor, w t, is the factor by which the equivalent dose in a tissue or organ t is weighted to represent the relative contribution of that tissue or organ to the total health detriment resulting from uniform irradiation of the body (icrp 1991b). In the past there a similar factor known as quality factor was used for this purpose. The icrp tissue weighting factors are chosen to represent the fraction of health risk, or biological effect, which is attributable to the specific tissue named.
2 When The Equivalent Dose Received By And Committed To One Of These Remainder Organs And Tissues Exceeds The Equivalent Dose Received By And Committed To Any One Of The Organs And Tissues Listed In Items 1 To 12, A Weighting Factor Of 0.025 Shall Be Applied To That Remainder Organ Or Tissue And A Weighting Factor Of 0.025 Shall Be Applied To.
14 rows adrenals, brain, small intestine, kidney, muscle, pancreas, spleen, thymus, uterus. Weight and the weighting factor. In radiation protection, a factor weighting the equivalent dose in a particular tissue or organ in terms of its relative contribution to the total deleterious effects resulting from uniform irradiation of the whole body.
In Particular, The Tissue Weighting Factor For The Breast Increased From 0.05 To 0.12.
The sum of all the tissue weighting factors used in effective dose determinations is 1.0. Tissue weighting factors according to icrp 103 (icrp 2007) tissue: The tissue weighting factor is a relative measure of the risk of certain serious stochastic effects that might result from irradiation of that specific tissue.
