However, students discovered that embedded in each CR image are digital communication in medicine (DICOM) attributes, which include S value and relative x-ray exposure
The American College of Obstetricians and Gynecologists recommends that women be counseled that x-ray exposure
from a single diagnostic procedure does not result in harmful fetal effects.
The researchers assumed there was no cut-off point below which X-ray exposure
cannot induce cancer.
Many patients with Crohn's disease are young, and receive repeated x-ray exposure
from serial enteroclysis examinations.
This increase in efficiency enabled a substantial reduction in x-ray exposure
levels without compromising image quality, and x-ray film manufacturers moved quickly to develop x-ray film that was sensitized to green light.
Even if the actual number is lower, there's strong evidence of a connection between X-ray exposure
and breast cancer.
In this experiment, three different species of bacteria in broth and water were exposed to relatively extreme environmental conditions consisting of x-ray exposure
, low temperatures, and a combination of both factors.
This hypothesis is not substantiated by finding a correlation between the number of physicians and the number of deaths from X rays unless one accepts the conjecture, or guess, that the number of physicians can be used as a measure of X-ray exposure
. No matter how attractive this notion may be, it remains a guess until tested and proved.
The NIST Lamperti chamber is designed for x-ray exposure
and air kerma measurements in the 10 kV to 60 kV region, but is generally used at NIST for the 10 kV and 15 kV qualities.
Tim Eden, Cancer Research Campaign professor of paediatric oncology in Manchester, is investigating the risks of X-ray exposure
in pre-term babies and said: "The research is very interesting and warrants further investigation."
He emphasized that the effect of X-ray exposure
But doctors try to limit patients' X-ray exposure
; high doses (no one's sure how much) can burn tissue and even cause cancer, Ramsey says.
