2007 Recommendations of the ICRP Change Basis for Estimation of the Effective Dose: What is the Impact on Radiation Dose Assessment of Patient and Personnel?

The revision of the parameters for effective dose calculation leads to higher doses and greater sex-specific differences for radiological examinations involving exposure of the breast. This effect should be considered when justifying any radiological examination. For the personnel, the new model results in higher effective doses due to increased emphasis on the organs in the head and neck region. Hence to optimize radiation protection of personnel, the use of radiation-protective shielding for this region becomes more important.
