How should we handle visitors and other patients in the same room as the patient during portable radiography?

The energy level used for medical radiography is generally low and attenuates sufficiently at a distance of about 1.5 m. The energy is almost zero at a distance of about 2 m. Radiation does not reach levels that could cause bodily effects in other patients in the same room. Create a system for reducing patient anxiety, such as by having a nurse explain such information in advance when the examination is requested, in addition to providing the information when the patient checks in to the hospital. If visitors are kept at a distance of 1.5 to 2 m, there should be no problems with radiation exposure, but normally patients prefer not to have non-family members see them during radiography, so handle the given situation accordingly.
