NOMAD Pro™ – Proven Safe

X-ray systems typically generate stray radiation when fired. Backscatter radiation from a patient’s jaw can reflect back at the operator or to other parts of the patient. Because of this, lead aprons and/or thyroid shields are usually used to protect the patient, and conventional X-ray generators are operated remotely, in order to protect the operator.

However, NOMAD Pro is designed with safety as the number one priority. The external backscatter shield and internal radiation shielding are specially designed to protect the operator from radiation exposure. In fact, the exposure from using NOMAD Pro™ is less than one percent of allowed occupational doses. NOMAD Pro is safe!

How does it work?

As mentioned, NOMAD Pro™ employs an external backscatter shield to protect the operator from reflected radiation. This shield produces a cone-shaped protection zone extending behind it. At the position where the operator stands, the zone has a diameter of more than six feet, enough to protect the operator’s entire body.

In addition, radiation shielding inside NOMAD Pro™ ensures that leakage from the x-ray source itself is virtually eliminated, protecting the operator’s hands and other areas close to the device.

How much exposure is too much?

Radiation is all around us, all the time. It varies with your lifestyle and where you live. Click here to find out how much exposure you receive in everyday living.

The average dose per person from all sources is about 360 mrems per year. International Standards allow exposure to as much as 5,000 mrems a year for those who work with and around radioactive material. You can see how NOMAD™, even with heavy use, results in minimal exposure for the operator.
