Portable Dental X Ray Machine Radiation Exposure

Sets performance criteria for them.

Portable dental x ray machine radiation exposure.

The x ray program registers approximately 17 000 radiation producing machines such as x ray machines. The x ray registration inspection and certification program exists to assure quality radiographs with a safe x ray facility environment for both the people of virginia and the operators of the equipment. To reduce operator exposure to backscatter radiation manufacturers of hand held x ray equipment should incorporate physical means to provide operator shielding or allow operation of the unit at a. Dose measurements were conducted using a dxtrr phantom and a water phantom.

Currently there are voluntary guidelines promulgated by the ncrp for dental radiation protection. To put it simply the amount of radiation from one adult chest x ray 0 1 msv is about the same as 10 days of natural background radiation that we are all exposed to as part of our daily living. A new hand held battery operated portable x ray system was tested for possible leakage radiation through the existing heavy metal compounds surrounding the x ray tube backscatter radiation through the lead filled acrylic shield attached at the end of the exit tube and patient exposure. The x ray tube and collimator are completely enclosed in a proprietary blend of metals that are designed to block radiation leakage.

Hand held portable x ray devices are increasingly used for intraoral radiography.
