Radiation Dose with CT Scan-Mayo Clinic

There have been a lot of misconceptions about the risks associated with radiation dosages and CT scans. Amy Hara, M.D., a radiologist at Mayo Clinic in Arizona, provides some real answers to questions surrounding radiation dose and when to have procedures such as a CT scan vs. MRI or other non-radiation tests.

Is there radiation in MRI? I have to get one every 3 months. Should I cut back?

@stormspottter Hello, thanks for your question. MRI is a technique that uses a magnetic field and radio waves to create detailed images of the organs and tissues within your body. MRIs do not use x-rays or radiation. Thanks again.

the acceptable dose for the public is 1 mSv per year, a x-ray worker is allowed 50 times more ionizing radiation, these x-ray workers are taking high pay for cancer. The IAEA and WHO and all American governments agree that there is no safe level of radiation. The people working in these x-ray depts are so unprotected as the shielding in these rooms are set to the lest expensive values thanks to alara. If I worked in these depts I would own my own dosimiter and not hide it behind my lead vest

Be careful CT scan can cause cancer.

Actually for professionally exposed (radiologist's ect) the max year dosage is 20mSv and for the general population is 10x less in all aspects/year. So 1-2mSv is the usual/year exposition. Regardless of the numbers i agree that 5-6mSv up to 10mSv for general population is far from dangerous in any way. The acceptable doses for professionals 20+mSv are 3-4X lower than needed for causing a chronic radiation disease and even farther for "dose dependent" diseases.

Thank's for this video Amy Hara
