Patients with bone scans can metabolize the radiation in their bodies as long as they drink more water and eat more fruits with high vitamin content. The half-life of the radiological agents used in bone scans is only a few hours, usually around 6 hours, and some drugs have a half-life of only 2-3 hours, which means that the maximum time these drugs stay in the body is about 6 hours, after 6 hours the drugs will be metabolized. The radiation dose of these drugs is also very low, significantly lower than the usual amount of chest CT scan, so compared to ordinary X-rays its radiation is minimal, there is no need to panic after doing a bone scan.
