Is It True That Cell Phones Emit The Same Kind Of Radiation As Microwave Ovens
And your car radio: The microwave oven was "discovered" when a lab scientist had a chocolate bar melt in his pocket when it was exposed to radio waves in the microwave spectrum. Radio waves come into your house for tv reception, to your car for radio reception, from you wifi router and to you cell phone. Recent studies have shown that there is no increase in disease following exposure to microwaves. ...Read moreSee 2 more doctor answers
Is there a different amount of radiation that comes from regular cell phones compared to smart phones?
Depends on phone: Cell/smart phones all have ratings with the sar ratings based on the electomagnetic radiation they emit in use. All must be rated <1.6w/kg and the ratings are readily available. I see some rated from.24-1.55 from the same company. Check with your retailer or phone site. ...Read moreSee 1 more doctor answer
1-is it true that electromagnetic radiation , from computers n mobile phones are bad for you, ?
2-is it true that computers emit ozone which is toxic
Ozone: I use ozone daily in my office. High voltage can make ozone. Lungs and eyes are less tolerant of ozone than other tissues. Do u smell it? However it may be improving your health. Ozone is used in europe subways and schools to reduce bacteria and virus in air. Ozone is very reactive and does not last long in air. I believe that if the amount was high enough to cause you harm you'd know it. ...Read moreSee 1 more doctor answer
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
No: Tv screens and monitors emit light radiation which is of course not harmful. This has been tested repeatedly and there is no evidence that harmful radiation comes from these sources. This is part of the scare tactics of junk science which erupts sporadically. ...Read more
If phones emit non ionizing radiation which don't damage dna, why is there speculation on phones causing cancer?
Speculation: There are many speculations on things that have no evidence. I tell people to be curious and critical. Being curious and naive is not helpful to individuals or society. Ask for the data, not just headlines. ...Read more
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
What is the difference between nuclear medicine radiation and ct/x-ray? Is it true that the only radiation you receive in nuclear medicine is the radioactive tracer that is administered into your vein? If so, does this radiation not accumulate as ct/x ray
Yes.: In nuclear medicine a radioactive "tracer" (e.g. Technetium) is injected into a vein and the gamma rays are emitted from the body and detected by a gamma camera placed against the body to create an image. The radioactivity decays over time and is also excreted from the body. With ct, the x-rays are passed through the body from an xray tube to create an image and do not reside in the body. ...Read moreSee 2 more doctor answers
Heard that perfumes contain toxic chemicals capable of remaining in the brain for decades once crossed the blood brain barrier, is this true?
I don't think so: Our world's full of causes, and an understandable fear of "chemicals" has prompted some people to demand a "perfume-free workplace." i don't want to get into any arguments here, but i think most healthtap members will tell you these fears are not evidence-based. The most inflammatory claim about neurotoxicity is a non-peer-reviewed poster. I'll add that i very much dislike artificial fragrances. ...Read more
No: The pop claim that they do is based on scientific illiteracy -- the radiation they produce isn't the ionizing kind that causes cancer, it's the low-energy stuff that's also emitted by a pet kitten. Unfortunately, when politics and fearmongering start, it's easy to do a bad epidemiologic study & scare people -- one had more of the cancers on the opposite side from the phone. It's dumb. ...Read moreSee 1 more doctor answer
Is it true that we are exposed to radiation all the time? That its in the air? Isn't that harmful? How to avoid it??
Low level exposure: is always present from the earth's rocks, and topography, but not when manmade events occur like Fukushima. Please post when you are 17 YO, and discuss this with your parents, and pediatrician to get the most up to date info. Thanks! ...Read more
Do medical x-rays such as CT scans kill the newborn cells when lots of radiation hits the body all together?
Not sure: I'm not sure what you're asking. Are you talking about fetal exposure during pregnancy or tests performed on a newborn? Radiation dose is cumulative over a lifetime. The dose is dependent on the type and number of studies performed. In addition, certain organs (such as ovaries) are more sensitive to radiation. ...Read more
No proof yet. : Unfortunately, the studies that exist on this topic are not designed or powered to adequately answer this question. There is a claim, based on some wistar rat studies, that certain types of cell phone radiation can have an effect of sperm morphology and maturation. These are not conclusive, and no human studies have shown this link. ...Read moreSee 1 more doctor answer
Not really: It won't damage minerals or proteins at all. Any cooking can reduce vitamin c content some and some other vitamins to a lesser extent. Boiling vegetables in water actually loses more good stuff into the water. The 'pop' claim that microwaving renders food far less nutritious is just something that folks made up because folks are likely to believe scare stories about new technologies. ...Read more
Not really: Microwaves are pretty safe. Over the life of one microwave, it may give off 5 miliwatts of microwave radiation per square centimeter within 2 inches of the microwave, which is very well below what the FDA deems unsafe. If you stand 20 inches away from the microwave in use, the radiation is only one-hundredth of the value given off at 2 inches. It is unlikely you will have detrimental effects. ...Read moreSee 1 more doctor answer
No: It makes no sense biologically. The radiation isn't of the wavelengths that damage molecules, let alone kill cells. The studies that supposedly show harm are retrospective surveys that invite recall bias -- i.e., junk. Our high-tech age is difficult enough without this kind of fearmongering. You should at least enjoy its benefits. ...Read more
