This blew my mind. Take a look at this new portable hand held battery operated X-Ray head. My first thought when I saw this was, “Wow she will get scatter radiation by standing so close!” Even though the exposure is very very low, dental staff members take many exposures per day. The Alabama guidelines are that you need to stand six feet away from the tube head to be ok. You know, stand outside the room. They say this thing is shielded and you’ll be ok. This device would be really great for overseas mission trips. The web site is www.aribex.com
