Radiation From Diagnostic Imaging Can Cause Cellular Damage – Dr. Rath Health Foundation

Early detection of health problems is very important in diagnosing or sometimes eliminating disease at its onset. Over the past decades, various imaging techniques such as X-rays, ultrasounds, MRI (magnetic resonance imaging) and CT or CAT scans (computerized-assisted tomography) have been developed and applied for diagnostic as well as therapeutic medical care. However, in recent years many doctors, and especially radiologists, have become concerned by overuse of certain diagnostic techniques, in particular those that expose patients to radiation.
Although infrequent use of X-ray or CT scans will not have adverse effects on a patient, multiple exposures to radiation even over a short period of time can cause serious damage to cells and increase risks of cancer, cardiovascular disease as well as many other diseases. In 2007 alone, the U.S. National Cancer Institute predicted that 29,000 future cancer cases could be linked to the 72 million CT scans performed in the country in that year alone. Despite such concerns and warnings, the use of diagnostic CT scans has skyrocketed in the U.S. over the past three decades from 3 million CT scans in the 1980s to 70 million in 2007 – this rate has doubled in just the past five years. More than 4-7 million American children are getting CT scans and the number continues to increase by 10% every year! It is quite common in the U.S. that almost everyone complaining of upset stomach gets an abdominal CT scan. The radiation from one such abdominal CT scan is approximately comparable to 200 chest X-rays or 1,500 dental X-rays.

Furthermore, CT scans are increasingly being used for regular health checkups as well. This is specifically true for imaging for arterial blockages to detect atherosclerotic heart diseases at six-month or yearly intervals. The rationale is that the radiation exposure for such a diagnostic CT scan is extremely small compared to a regular CT scan. According to an estimate, a regular CT scan exposes patients to at least 150 times the amount of radiation from a single chest X-ray.
