UNLABELLED: A new generation of reference computational phantoms, based on image-based models tied to the reference masses defined by the International Commission on Radiological Protection (ICRP) for dose calculations, is presented. METHODS: Anatomic models based on nonuniform rational b-spline modeling techniques were used to define reference male and female adults, 15-y-olds, 10-y-olds, 5-y-olds, 1-y-olds, newborns, and pregnant women at 3 stages of gestation, using the defined reference organ masses in ICRP publication 89...

Permanent prostate brachytherapy patients are generally told to limit their time around children and pregnant women. However, there is little data available to validate the instruction. For the skin effective dose rate, ion chamber survey meter model 451B-DE-SI was used. The meter was scanned at the point of 4.5, 20, 50 and 100 cm from the skin surface in each plane. Life time exposure was calculated from the average anterior data. At the point of 4.5 cm from the anterior skin surface, the lifetime equivalent dose was 46...

PURPOSE: To use radiation exposure rate measurements to determine patient-specific radiation safety instructions with the aim of reducing unnecessary precaution times and to evaluate potential doses to members of the public. METHODS AND MATERIALS: Radiation exposure rate measurements were obtained from 1279 patients with Stage T1-2 prostate cancer who underwent transperineal (125)I or (103)Pd seed implantation from January 1995 through July 2008. An algorithm was developed from these measurements to determine the required precaution times to maintain public effective doses below 50% of the limits for specific exposure situations...

OBJECTIVES: To assess the prevalence of and risk factors for urinary (UI) and fecal (FI) incontinence in adults in long-term care (LTC) settings and in the community, the effectiveness of diagnostic methods to identify adults at risk and patients with incontinence, and to review the effectiveness of clinical interventions to reduce the risk of incontinence. DATA SOURCES: MEDLINE (PubMed), CINAHL, and Cochrane Databases. REVIEW METHODS: Observational studies were reviewed to examine the prevalence and incidence of UI and FI and the association with risk factors...

REVIEW
(no author information available yet)
The use of permanent radioactive implants (125I or 103Pd seeds) to treat selected localised prostate cancer patients has been increasing rapidly all over the world for the last 15 years. It is estimated that more than 50,000 patients are treated this way every year in the world, and this number is anticipated to increase in the near future. Although no accidents or adverse effects involving medical staff and/or members of the patient's family have been reported to date, this brachytherapy technique raises a number of radiation safety issues that need specific recommendations from the ICRP...
