Accreditation Is Important For Radiology Centers
Always ask if the imaging facility has been accredited. The Centers for Medicare and Medicaid Services has approved three bodies to accredit diagnostic imaging programs: the American College of Radiology, the Intersocietal Accreditation Commission and The Joint Commission. There are five requirements for accreditation:
So far, this accreditation process is mandatory for outpatient facilities only, but it is very likely to become mandatory for hospitals, too. The University of Michigan has received American College of Radiology accreditation for many of our facilities already, both in the outpatient setting and at the hospital. Soon, all of our facilities will be accredited.
Ionizing Radiation And Cancer Risk
We’ve long known that children and teens who receive high doses of radiation to treat lymphoma or other cancers are more likely to develop additional cancers later in life. But we have no clinical trials to guide our thinking about cancer risk from medical radiation in healthy adults. Most of what we know about the risks of ionizing radiation comes from long-term studies of people who survived the 1945 atomic bomb blasts at Hiroshima and Nagasaki. These studies show a slightly but significantly increased risk of cancer in those exposed to the blasts, including a group of 25,000 Hiroshima survivors who received less than 50 mSv of radiation an amount you might get from three or more CT scans.
The atomic blast isn’t a perfect model for exposure to medical radiation, because the bomb released its radiation all at once, while the doses from medical imaging are smaller and spread over time. Still, most experts believe that can be almost as harmful as getting an equivalent dose all at once.

Comparing Future Risks With Current Benefits
Comparing the risk of future cancer with the current benefit from an imaging study is not a like-for-like comparison. The risk from CT radiation is the risk of an event that, if it occurs, will occur many years in the future. A loss of life expectancy calculation provides a more meaningful estimate of risk than does mortality. Epidemiologic data indicate that radiation-induced cancers occur after a latency period, and at a similar age as naturally occurring cancers, predominantly at ages 4585. If the likelihood of dying of radiation-induced cancer is 1/4000, the mean age of cancer development is 65years , the mean age of cancer death is 70years, and the projected lifespan is 85years, then the expected loss of life expectancy from a radiation-induced cancer is 15years. The population-averaged loss of life expectancy is 15yearsÃ1/4000=1/267 of a year, or less than 2days.
CT scans are often obtained in patients with life-threatening diseases, and if disease-related mortality is taken into consideration, the risk of radiation-induced cancer and the loss of life expectancy from radiation-induced cancer are smaller since these patients may not live long enough to develop these cancers. In a study of CT in young adults the observed risk of a patient dying within 5years from their underlying disease was one to two orders of magnitude greater than the theoretical risk of dying from a cancer induced by CT.

When Ct Scans Are Used
CT scans can produce detailed images of many structures inside the body, including the internal organs, blood vessels and bones.
They can be used to:
- diagnose conditions including damage to bones, injuries to internal organs, problems with blood flow, stroke, and cancer
- guide further tests or treatments for example, CT scans can help determine the location, size and shape of a tumour before having radiotherapy, or allow a doctor to take a needle biopsy or drain an abscess
- monitor conditions including checking the size of tumours during and after cancer treatment
CT scans wouldnât normally be used to check for problems if you donât have any symptoms .
This is because the benefits of screening may not outweigh the risks, particularly if it leads to unnecessary testing and anxiety.

Top 10 Foods To Help You Naturally Detox From Radiation
You might be reading this article and thinking that it would really only apply if there was another nuclear war or if you were somehow accidentally exposed to radiation. But did you know that radiation fallout is actually all around you?
You probably cant remember a time when acid rain was not a problem. Air pollution is picked up by the rain and fog and brought to the ground.
And lets not forget the earthquake and tsunami that hit Japan in 2011 and damaged the Fukushima power plant, leaking radiation into the air and water. This event is NOT over, folks it is ongoing. Radioactive elements were released into the air and water. These elements accumulate at each step of the food chain. Once inside the body, radioactive elements are called internal emitters, and these migrate to specific organs typically, the thyroid, brain, liver and bones.
Radioactive isotopes have been found in rainwater in Minnesota and a few other states. Even if you feel that you are safe from fallout, there are many other risk factors that expose you to radiation. These include airport security cameras, dental X-rays, medical X-rays and radioactive particles in the air. Speaking of medical tests, Pet/CT scans are a very precise tool that can help diagnose many disorders, but this type of scan is a huge dose of radiation. If you have cancer, you might be getting regular doses of high intensity radiation.

Ways To Reduce Your Radiation Levels
1. Up your seaweed consumption and add in blue green algae, spirulina and chlorella: binds to toxic substances, making it easier to excrete them from your body
2. Protect yourself from mobile phone and computer emissions: Reduce the hours spent in front of your computer or on your phone. Or buy a radiation protection shield to stick on your phone or computer and minimise the electromagnetic radiation.
3. Consult a homeopath: Both Ainsworths and Nelsons, Londons world renowned homeopathic pharmacies, have developed specialist anti-radiation formulas. Ainsworths also has a mobile phone radiation tablet. Rad Brom cadmium sulphuratum, arsenicum album and Ruta graveolens are often prescribed.
4. Up your anti-oxidants and choose your supplements carefully: Radiation releases free radicals which damage DNA, protein and fats. Supplement with vitamins C, E and D and selenium, which are all powerful anti-oxidants that will help guard against free radicals and protect against radiation fallout and cancer. Eat more fruits and vegetables, particularly broccoli, cabbage, blueberries, sweet potatoes, cherries which have high levels of antioxidants.
Alpha lipoic acid protects against radiation damage. Cysteine, which is an amino acid, also wipes out free radicals. Supplement with papein, made from papaya. Beetroot will detoxify your body. Radiation poisoning breaks down the haemoglobin in your blood: beetroot rebuilds it.

How Much Radiation Is The Average Person Exposed To In Day
We are constantly exposed to radiation from a number of sources, including radioactive materials in our environment, radon gas in our homes, and cosmic rays from outer space. This is called background radiation and it varies across the country.
The average American is exposed to about 3 mSv of radiation from natural sources over the course of a year. But background radiation exposure varies throughout the United States, and the world.
The largest source of background radiation is radon, a natural gas found in our homes. Radon levels vary greatly from one part of the country to another.
Location also plays a role because the earths atmosphere blocks some cosmic rays. This means being at a higher altitude increases a persons exposure. So, people living in the higher parts of New Mexico and Colorado are exposed to more radiation per year than people living closer to sea level. And a 10-hour airline flight increases cosmic ray exposure by about 0.03 mSv.

Recent headlines on the appalling misuse of CT scans and X-ray imaging have finally drawn attention to their lethal effects. Routine diagnostic radiation exposure may account for nearly 30,000 new cancer cases each year. Here we detail an optimal radioprotective nutritional regimen, including polyphenols, trace minerals, and antioxidant compounds.
Scientifically reviewed by: Dr. Shanti Albani, ND, Physician, in May 2022. Written by: Robert Klein.
In hospitals and doctors offices around the country, millions of innocent patients are unknowingly exposed to excessive radiation. The main culprit is the computed tomography scan which exposes patients to the equivalent amount of radiation received by atomic bomb survivors in the low-dose range.1
Published scientific studies document that these excessive amounts of radiation will result in catastrophic numbers of new cancers due to DNA mutation.1-3 Epidemiologists estimate that as many as 29,000 new cancers could be related to CT scans performed in the US in 2007 alone.2 There are now approximately 70 million CT scans performed every year, up from a mere 3 million in 1980.4,5
What follows is an analysis of recent studies showing how certain remarkable nutrients can ward off many dangers associated with medical-based diagnostic radiation exposure.

Will It Lead To Cancer
What are the chances that the X-rays from a scan will end up causing a problem? It depends on your age, gender, and the part of your body that’s being scanned. Overall, your odds are very low — the chance of getting a fatal cancer from any one CT scan is about 1 in 2,000.
Some organs are more sensitive to radiation than others. It tends to do more damage to cells that grow and divide quickly. The breasts, lungs, thyroid gland, and bone marrow all have fast-dividing cells, so they are more sensitive than other body parts, like the brain.
The possibility of cancer is slightly higher in women than in men. It’s also higher in kids, because they’re growing and their cells are dividing faster than those in adults. Children also have more years ahead of them in which they could get cancer from radiation.
If You Cant Take A Shower:
- Wash your hands, face, and parts of your body that were uncovered at a sink or faucet. Use soap and plenty of water.
- If you do not have access to a sink or faucet, use a moist wipe, clean wet cloth, or a damp paper towel to wipe the parts of your body that were uncovered. Pay special attention to your hands and face.
- Gently blow your nose, wipe your eyelids, eyelashes, and ears with a moist wipe, clean wet cloth, or a damp paper towel.
- Put the used wipes, cloth or towel in a plastic bag or other sealable container and place the bag in an out-of-the-way place, away from other people and pets.

How Much Does An Imaging Test Expose A Person To Radiation
The amount of radiation exposure from an imaging test depends on the imaging test used and what part of the body is being tested. For instance:
- A single chest x-ray exposes the patient to about 0.1 mSv. This is about the same amount of radiation people are exposed to naturally over the course of about 10 days.
- A mammogram exposes a woman to 0.4 mSv, or about the amount a person would expect to get from natural background exposure over 7 weeks.
Some other imaging tests have higher exposures, for example:
- A lower GI series using x-rays of the large intestine exposes a person to about 8 mSv, or about the amount expected over about 3 years.
- A CT scan of the abdomen and pelvis exposes a person to about 10 mSv.
- A PET/CT exposes you to about 25 mSv of radiation. This is equal to about 8 years of average background radiation exposure.
Keep in mind that these are estimates for an average-sized adult. Studies have found that the amount of radiation you get can vary a great deal.
Radiation Risk From Medical Imaging
There’s always questions about radiation exposure from medical imaging. Patients want to know if radiation from mammograms, bone density tests, computed tomography scans, and so forth will increase their risk of developing cancer. For most women, there’s very little risk from routine x-ray imaging such as mammography or dental x-rays. But many experts are concerned about an explosion in the use of higher radiationdose tests, such as CT and nuclear imaging.
Over 80 million CT scans are performed in the United States each year, compared with just three million in 1980. There are good reasons for this trend. CT scanning and nuclear imaging have revolutionized diagnosis and treatment, almost eliminating the need for once-common exploratory surgeries and many other invasive and potentially risky procedures. The benefits of these tests, when they’re appropriate, far outweigh any radiation-associated cancer risks, and the risk from a single CT scan or nuclear imaging test is quite small. But are we courting future public health problems?

What About Radiation From Imaging Tests And Children
Children are more sensitive to radiation than adults. Because of this, health care providers are careful to reduce radiation exposure to pediatric patients for imaging tests that use radiation. Still, parents can and should ask questions before any imaging tests are done.
Here are some questions to ask:
- Why does my child need an imaging test?
- What type of imaging test do you think my child needs?
- Does it use radiation?
- Are there other options that dont use radiation?
- Can the amount of radiation used be adjusted for my childs size?
Again, the benefits of the test should outweigh the risks of radiation exposure.
You may also want to keep a medical imaging record to track your childs history of imaging tests and share it with their health care providers. An English version for children can be found online at www.imagegently.org.
