Radiation Protection Dosimetry, 2014
Dose-area product-to-effective dose (E) conversion factors for chest, abdomen and abdomen-chest neonatal radiographs were computed. Seven patient models in the Monte Carlo software, PCXMC, were defined, representing neonates ranging in weight from 0.5 to 6.0 kg.

Dose area product reference levels in dental panoramic radiology.
Radiation Protection Dosimetry, 2004The purpose of this study was to measure DAP (Dose Area Product) values in panoramic radiology with the use of a DAP meter, to determine corresponding reference levels, and to compare DAP between panoramic and intraoral radiology. DAP was measured in 62 panoramic X-ray units for 3 types of exposure (male, female and child) and in 20 intraoral X-ray ...

Radiation Protection Dosimetry, 2012
In this study, diagnostic reference levels (DRLs) were suggested and patient doses were analysed through the dose-area product value in dental radiography. In intraoral radiography, at three sites, i.e. molar, premolar and incisor on the maxilla and acquired third quartile values: 55.5, 46 and 36.5 mGy cm(2), respectively, were measured.

Correlation of patient skin doses in cardiac interventional radiology with dose-area product.
The British Journal of Radiology, 2000The use of X-rays in cardiac interventional radiology has the potential to induce deterministic radiation effects on the patient's skin. Guidelines published by official organizations encourage the recording of information to evaluate this risk, and the use of reference values in terms of the dose-area product (DAP).

Digital radiography allows for image manipulation, giving radiographers the ability to adjust the grey level of the image using latitude-algorithm. In doing such, patients receiving unnecessary radiation-dose often goes undetected.

Histerosalpingography (HSG) remains the dominant diagnostic tool for investigation of infertility in women. Conversion factors used to estimate effective (E) and organ doses (HT) from air Kerma area product (KAP) are needed to estimate patient doses in HSG, performed with state-of-the-art fluoroscopic X-ray systems with digital detectors. In this study,

The Dose-area Product and Assessment of the Occupational Dose in Interventional Radiology
Radiation Protection Dosimetry, 2001This study used dose-area product (DAP) data to determine the relationship between the dose received by radiologists and the DAP. The working conditions were simulated by phantom measurements. The doses of scattered radiation were measured using various scattering angles, distances and tube voltages.

Calibration frequency of dose–area product meters
The British Journal of Radiology, 2001Calibration of patient dose monitoring devices in diagnostic radiology has become increasingly important in the light of new legislation that requires monitoring of patient dose against local and national diagnostic reference levels. An investigation was conducted into the long-term stability of 41 dose-area product (DAP) meters over a period of ...

PURPOSE To provide current data on average air kerma-area product (PKA ) and effective dose (E) for non-cardiac interventional fluoroscopy procedures and suggested values of dose coefficients (DCE ) for conversion of PKA to estimates of effective dose.

Skin dose and dose–area product values in patients undergoing intracoronary brachytherapy
The British Journal of Radiology, 2003Entrance skin doses, dose-area product (DAP) values, fluoroscopy times and digital cine acquisition data were measured for 86 patients undergoing intracoronary brachytherapy procedures with beta sources, to estimate risk of skin injuries. Interventions were carried out in three dedicated X-ray interventional cardiology rooms equipped with X-ray systems
