An independent study presented at the 2009 Conference of Radiation Control Program Directors (CRCPD) concluded that the Nomad handheld dental x-ray system produces radiation exposure doses so low that the vast majority of users receive no measurable radiation dose, according to Aribex, which manufactures the Nomad system.
This conclusion contradicts the common misperception that operator exposure would be higher with a handheld x-ray system, the company said.
The study also found that the image resolution and contrast of the Nomad were superior to the wall-mounted system tested, and the leakage and scattered radiation were lower. In addition, the study reported that additional operator protection measures, such as the use of lead aprons or stands, are not warranted. This is largely due to improved shielding techniques incorporated into the Nomad, according to the study.
The paper, "Image Quality and Radiation Dose Comparison for Intraoral Radiography: Hand-held, Battery Powered versus Conventional X-ray Systems," was delivered at the May CRCPD conference in Columbus, OH, and authored by Edgar Bailey, MSEHE; Joel Gray, Ph.D.; and John Ludlow, D.D.D.
