Radiation damage: The past is the past. Antioxidants and healthy living are the best recommendations for you. If down the road you get systemic symptoms such as weight loss or chronic headaches please see your physician. An MRI is a radiation free test that if you need one you should have instead of ct or x-ray. Relaxation techniques may be of benefit to you as well. ...Read more

Does MRI Radiation can be danger as Cell phone radiation since both work on electromagnetic?

Does MRI Radiation can be danger as Cell phone radiation since both work on electromagnetic?

Frequency is a key: Issue because energy per photon correlates with the frequency of EMR. Study: https://en. Wikipedia. Org/wiki/Electromagnetic_radiation. Additionally, issue is not just EMR energy transmitted but absorbed (versus just passing through without apparent effect) combined with biologic responses, thus no one 100% understands. MRI (actually NMRI) uses intense magnetic fields & RF EMR, not ionizing like CT. ...Read more

What is the dangers in radiation of gamma rays and x-rays?

What is the dangers in radiation of gamma rays and x-rays?

Can cause cancer: Radiation from various sources has the potential to cause cell damage leading to Cancer. The risk is based on the total dose of radiation received by a subject. Moderate doses are commonly used to treat cancer and low doses are commonly receeived when doing X-ray imaging of the body but these are felt to be safe (for medical uses) ...Read more

I am having 3rd Ct scan in 4 years. One for kidney and two of brain for vertigo. Dr says I need third. Am I in danger of radiation?

No: Unnecessary radiation should always be avoided. For diagnostic X-ray use, the minimal radiation risk is outweighed by the medical benefits. You can calculate your risk at xrayrisk. Com. ...Read more

Is the radiation from an X-ray dangerous?

The amount: Of exposure for diagnostic x-rays is considered safe. Any increased exposure to radiation contributes to a cumulative theoretical lifetime risk, including flying on a plane, but the risk from a single x-ray is miniscule. That said, the increased risk is zero if you don't have the x-ray, which is why x-rays should only be utilized when medically necessary. ...Read more

Is it true that radiation from cell phones is dangerous?

Is it true that radiation from cell phones is dangerous?

Good question: The answer is not certain. However, I know of a surgeon at a university who claims that he is operating more for acoustic neuroma (a tumor associated with the hearing mechanisms) that he no longer considers it rare. The trouble is that there are so many other factors. Personally I think that cell phones are overused and may be damaging to some. ...Read more

What are the sources of ionizing radiation. I heard its dangerous thanks?

Good question: 80% of global average exposure of humans to ionizing radiation comes from nature (cosmic radiation, radon gas...). The remaining 20% results from exposure to human made radiation sources like medical imaging, air travel and nuclear power plant to mention a few. In medical imaging today in particular there is a big empahsis on reducing the radiation dose to as low as reasonably achievable. ...Read more

Do millimetre wave body scanners at airports produce radiation and is there any danger?

Difficult to answer: Scanners do produce electromagnetic radiation but it is non-ionizing. Ionizing radiation like x-rays are dangerous to DNA. Regard the millimetre wave radiation radiation likely it does not cause DNA damage to your tissue. There are some studies that show DNA damage outside of the cell but not really inside of the cell per say. Basically your ok for the very short time your in the scanners. ...Read more

How dangerous is cell phone radiation?

It's not: This isn't the wavelength that damages molecules. The studies that purport to show danger are obvious junk science -- retrospective work. In the biggest one, the tumors were more common on the opposite side from the phone. Other junk cancer scares proved to be secretly funded by tobacco companies and I wouldn't be surprised if this was what's happening here. Enjoy your technology. ...Read more

Will a hida nuclear scan expose me to dangerous radiation?

Will a hida nuclear scan expose me to dangerous radiation?

No: All imaging tests that expose a patient to radiation should only be performed for certain conditions/symptoms. That is called appropriate use.

Medical radiation is a useful tool, but it should not be used unless necessary to help make a diagnosis.

Radiology is always trying to balance radiation dose with image quality. This is called alara - as low as reasonably achievable. ...Read more

I use an ipad tablet and computer for hours a day. Is there danger with wifi radiation use for extended amounts of time?

No evidenceofdanger: So far, there has not been any evidence to suggest using wireless devices causes any issues. In reality, we are bombarded with the signals all the time we are around wifi whether we have a device or not. So if you have a router in your house, it is always sending out some level of signal that will be getting to you. There has not been any studies to suggest this is doing any harm to us. ...Read more

Is there any dangers of cell phone radiation on babies?

Zero: There is no documented risk of cell phones to babies. There are always a few who like to speculate that anything we do has risk. We have all sorts of radio waves and other radiation generated from the sun that travels through us on a daily basis whether we have a decoder/receiver unit for them or not. ...Read more

Why MRI test does not count danger if it use same type of radiation as cell phone?

Why MRI test does not count danger if it use same type of radiation as cell phone?

Think about it.....: Think about the time exposure issue - if nothing else. Actually the probability that it's the exact same type is low, but... Most will have no more than a very few MRIs in their lifetime and most spend from an hour to several hours a day on their cell. That's often 365 days per year. It's not hard to see a difference. ...Read more

Had nuclear stress about 13 years ago don't remember meds used! Had HIDA 2 yrs ago plus annual mammos. Too much radiation? Nuclear dangerous?

Nuclear stress test: It would be unusual for a 33 year old woman to have a condition where a nuclear stress test was helpful. The effects of radiation exposure are measured in very small numbers -- while not zero, the risk of a radiation side effect is quite low from the kinds of diagnostic tests you've had. The goal is to keep radiation exposure as low as reasonably possible, while using tests when needed. ...Read more

What's the amount of radiation from abdominal X-ray in kids? How danger it is?

It is not: Dangerous. The total effective radiation dose is about 0.7 mSv. The theoretical increase in lifetime risk for this dose is about. 01% or 1 in 10000. Keep in mind that this is a theoretical risk based on extrapolation models.....there is no hard evidence that radiation doses this low have caused any cancers. ...Read more

I'm a 30 year old male. I had one CT scan done without contrast and now have to do one with contrast, is this a dangerous amount of radiation?

I'm a 30 year old male. I had one CT scan done without contrast and now have to do one with contrast, is this a dangerous amount of radiation?

Benefit ;: Risk depend on indication for studies. We tend to select who to do both. Many scans are now low dose. It's best to have a family doctor that knows you and decides when to do ct's rather than er which does more. The risk is population based, trivial increase for individual (1 in 10 thousand to 2/10k). ...Read more
