Also, consideration of patient size and demographics enable effective
organ dose calculations and patient risk assessment.
A PC program for estimating
organ dose and effective dose values in computed tomography.

Organ dose calculation in medical x ray examinations by the program PCXMC.
But a 2003 paper coauthored by David Brenner, director of the Center for Radiological Research at Columbia University School of Public Health, claims that the atom-bomb survivor data work well for low-dose extrapolation because they're drawn from large cohorts with well-defined exposures and complete followup.(9) And those data, Brenner says, show a statistically significant trend of increasing cancer risk with increasing
organ dose between 5 and 100 mSv.
A chest CT delivers an
organ dose to the breast equal to about 15 sets of mammograms.
The overall discussion about pregnancy and radiation dose is not consistent, and in fact, the authors seem to switch between effective dose and
organ dose with significant errors.
For example, does the marker of exposure relate to an exposure dose, an internal dose, a target
organ dose, or a biologically effective dose?
Organ doses measures through phantoms provide direct mechanism to estimate doses for patients undergoing radiological procedures [3].
Children are at particular risk because of their longer life expectancy, more active cell division, and higher
organ doses at a lower body mass (Chong et al., 2010).
It also incorporates recent developments in decontamination methods and the decorporation of radionuclides in contaminated people; and draws from publications of the International Commission on Radiological Protection for data and biokinetic and dosimetric models of
organ doses, total-body and organ retention values, and excretion rates of radionuclides.
