Hi I hope I'm not posting under the wrong forum but I'm pretty sure this is physics related. If you go to have an X-ray, in the film there will be information detailing the dosage you just received. However I encountered a rather unusual one like this: 70kV 100mAs 100mS -- dGycm2 El_s:300 As far as dGycm2 goes, the figure following it should well below 1, most likely 0.2 or something, yet it has 300. What IS that? The X-Ray wasn't done in the US. My apologies again if it has been posted under the wrong subforum.
