The radiation dose of taking a DR film is not very big, take a chest film for example, the radiation dose of taking a chest film is about 0.1mSv, this radiation dose is very low, compared with the background radiation that natural people receive every year, the background radiation is about 2mSv, the radiation dose of DR film is undoubtedly very small. If you compare it with taking one CT scan, the lowest dose of one CT scan is about 2mSv, that is, the radiation dose of one DR film is about 1% of one CT film, so don’t worry about the radiation dose of DR film.
