Hi
I have an assignment on scatter radiation, does anyone have any information about scatter radiation that comes form a chest xray ie how far do nurses have to be away from a portable chest?

thanks Jacques

Are you talking about " THE INVERTED SQUARE RULE " Where basically for every 6 ft ( 2metres ) the dose is halved from the scatter??? That's how I always understood it to be. If you're allowed to stand behind the mobile (squatted, or whatever ) and they are over double the distance you are..... 1  out of 2 found this valuable. Do you?

I believe it is the "Inverse Square Rule".

..."Where basically for every 6 ft ( 2metres ) the dose is halved from the scatter"... I think the rule you are thinking of is the rule of thumb that says that dose from scatter radiation is negligible at 2m. To say that every 2m, the dose is halved is completely wrong. If you double your distance, you decrease the dose by a quarter, not a half (hence the square in the inverse square rule). Increasing the distance from the source by 2m would only decrease the dose by half if the original distance was 482cm

Thanks for that. You can certainly tell I'm not a tutor.... Sorry for the misquote.
I always remember the nurses always going berserk, running in all directions, leaving the poor patients wondering if they really need the x-ray... It used to make me laugh!! As you can judge by the poor memory skills, it was a while ago now.
Thanks for keeping me honest, and its nice to know that people are reading these posts... 1  out of 1 found this valuable. Do you?
