Hi

Hope someone can help. I work in an old health clinic on the eastern sea board. My job is having a dental xray clinic next week all day! in the room above where I work! I have serious doubts about this as the floor of this room is only standard floorboard and the ceiling above my head is only standard plasterboard. These are over 40 years old.

My question is can xrays which are standard in dental practices penerate these materials - even slightly over the course of hours?

Probably, but I've never heard of a radiology room that was leaded on the ceiling. When an x-ray is taken, the radiation spreads out exponentially, so your exposure decreases dramatically the more distance you put between yourself and the source. I wouldn't worry about it.

Thanks for that. Though as I'm stuck in the room below this xray clinic I'm worried about the risk as the clinic will be all day and its floor is not leaded! Funnily their door is.

Just to clarify I'm not a radiologist or dentist and I'm not connected to this clinic, its just that I happen to be in the room below this clinic at the time.

The factors that effect radiation are: 1) Time 2) Distance 3) Shielding. As long as you are in another room, you should be quite safe. One of the reasons the operator always stands behind a wall when taking X-rays is to prevent occupational exposure. The machines and sources are shielded and calibrated (and regularly inspected) to control any random exposures.

IIRC, the guns are shielded on the sides, so the beam is very directional. Unless someone's jaw drops on the floor, you are probably out of the line of fire.

Doesn't answer the question. The person in the office below would be exposed over a long period of time. The X-ray technician or hygienist stands behind a wall because of the many days or even years of exposure. The ladies concern is valid and warrants further investigation. How much is the flooring and ceiling material blocking X-ray's? If it wasn't a good safety practice for a hygienist to stand behind a wall why would they bother? Because long term exposure is a risk, so your concern is valid.

According to this website (https://www.aegisdentalnetwork.com/i...stants-at-risk), dental health care workers need to stand at least 6 feet away from the instrument or behind a wall. Will you be more than 6 feet from the machine? Here's another site that you might find informative: XrayRisk.com : FAQ
