There is little radiation from DR photography. DR for digital X-ray shooting, is the use of electronic dark box X images directly into digital images, used for lung disease and skeletal system examination, for clinical diagnosis. Although the radiation dose of DR filming is not large, there is also a certain amount of radiation, for the instantaneous discharge, compared with the CT radiation is very small. The general public can not worry about the harm caused by radiation to the body when they undergo DR filming, which is currently being improved in terms of defense measures and machine performance, and the radiation dose is very low. However, if you are preparing for pregnancy or are already pregnant and need to undergo a DR examination, you should only consider a DR examination after your doctor has made a comprehensive assessment of the pros and cons of doing so. DR radiation may lead to an increase in the risk of neurological and hematologic abnormalities in the fetus, so women who are preparing for pregnancy or are already pregnant should avoid exposure to toxic and hazardous substances. It is advisable to consult your doctor regarding the amount of radiation exposure from the first DR film.
