CT scans should be handled with care because of the radiation involved. In fact, in many cases they shouldn't be done at all - especially full-body scans on apparently healthy people with no indicators of health problems.
It shouldn't take news of the fall-out from the Japanese nuclear meltdown to remind health care providers that radiation levels must be monitored closely. This is especially true when children are involved. Children's cells divide more quickly than adults, making kids more vulnerable to the effects of radiation.
When applied to medicine, technology can be a blessing - or a curse. Under the principle of "first, do no harm," potential curses should be recognized so that proper precautions can be taken against medical malpractice.
