“If an individual worked 250 days/ year [5 days/wk X 50] the Nomad dose would be about 0.0005 mSv/day at 0.12 and 0.0012 mSv/day at 0.3. That is 0.5 – 1.5 µSv / day. Compare that number to daily background of 3 µSv to 8 µSv/day for background (the 8 µSv/day would include Radon exposure).
“Using the 5 mSv as the dose where an occupationally exposed person must wear a monitoring device, then 5 mSv/0.12 = 41.7X lower. At 5 mSv/0.3 = 16.6 X lower, and if you choose the Maximum Permissible Dose for Occupationally exposed persons at 50 mSv/year then the numbers really pop at 417 to 166 X lower!” – John W. Preece, D.D.S., M.S., Professor Emeritus, Division of Oral and Maxillofacial Radiology, Department of Dental Diagnostic Science,The University of Texas Health Science Center At San Antonio
“From my measurements, and calculations using estimates of “worst case” workloads, if the instructions are followed there is little risk of operators receiving a dose above that allowed to the general public, and there is no requirement to wear a protective garment. With digital detectors, the dose will be 50% lower.” Mammographic Physics Consulting Group, Evaluation and testing of Nomad Pro Hand-held Intraoral X-ray System – ., G.E. Mawdsley, FCCPM, P. Phys., and M.J. Yaffe, Ph.D., FAAPM, April 2010
“The Nomad Pro System portable x-ray generator enables radiography virtually anywhere treatment is rendered, in or out of traditional office settings. It has proven particularly valuable in emergency treatment outside clinics and in humanitarian outreach programs, and has an established record of efficacy and safety.”

“Use of the NOMAD results in lower staff doses compared to wall-mount systems. Additional measures, e.g., use of stands or lead aprons, are not warranted.”
Image Quality And Radiation Dose Comparison For Intraoral Radiography: Hand-Held, Battery Powered Versus Conventional X-Ray Systems, Presented at CRCPD Annual Meeting May 2009, Edgar Bailey, M.S.E.H.E., C.H.P., Joel Gray, Ph.D., John Ludlow, D.D.S., May 2009
“If used according to instructions, the NOMAD Dental meets requirements.”
Measurement of Dose-Area-Product in Relation to Exposure Time for the Aribex NOMAD Dental X-Ray System, and Estimation of X-ray Exposure for Operating Personnel during Handheld Use of the Apparatus, LPS-Berlin, (TÜV NORD Röntgentechnik), Dr. J. Engelhardt, Dr. I. Lehmann, & Mr. Goerge, November 2008
“The results of this comparison of dental staff doses between the NOMAD handheld intraoral X-ray system and conventional wall-mounted intraoral X-ray systems indicate that the staff doses for the handheld systems are significantly less than those for wall-mounted systems. Consequently, there should be no concern about the use of NOMAD handheld dental intraoral x-ray system.”
Dental Staff Doses With Handheld Dental Intraoral X-Ray Units by Joel E. Gray, Edgar D. Bailey, and John B. Ludlow, Health Physics Society Journal, February 2012.
“Patient dose was reduced by 63% [when using the NOMAD and] operator dose was indistinguishable from background dose.”
(Phillips BJ, Ludlow JB, Platin E, Mauriello SM) This study has been accepted for oral presentation by the American Association for Dental Research during their March 2012 annual meeting.
“Our data have shown that the NOMAD presents risks that are no greater than with standard dental radiographic units to the patient or operator and the measured doses are well below recommended levels.”

“Interestingly, it was difficult to produce a “blurry” image due to movement, suggesting that the Nomad is easy to keep stable, even at 0.5 sec exposures.” Gammasonics Institute for Medical Research – April 2006 – Bruce Waters, Senior Radiographer, Westmead Centre for Oral Health, Westmead Hospital, NSW Australia
