Respectful Sir/Madam, Have come to know that x-rays leads to cancers in a human due to radiation. In that case, how many x-rays are safe for an individual? At the time of covid pandemic, most of them took nearly 10-15 chest x-rays and CT scans as they were affected with the virus and been prescribed by the doctors for 10-15 days continously. On an average, If a person in his lifetime takes nearly 30-40 x-rays, then does that leads to cancers? Please let know the details kindly. Thanking you in anticipation,
