Not that we know: The radiation energy from a cell tower is very low unless you are on the tower at the antenna. The current controversy is whether cell phone itself can cause brain malignancy since they are held close to your head while they are being used. The jury is still out on the question but prudence suggests you use your cell phone on speaker or use a blue tooth ear piece which generates lower radio ener. ...Read moreSee 2 more doctor answers
Will walking through the radiation oncology department expose me to dangerous levels of radiation?
CT scans: If there is an alternative to imaging the area such as MRI, then we prefer MRIs. There are some studies looking for bony problems that CT scan works better than MRI. Also in some settings, such as an emergency, if CT can be obtained more quickly or MRI not available, then CT is the test. How badly do you need the images and how soon are parts of the equation. ...Read more
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
No: That's one more scare story by somebody who doesn't understand the difference between the natural radiation that electronic devices and everything else produce, and the ionizing radiation that causes cancer. A bad epidemiologic study can "show" anything based on recall bias. Enjoy today's technology without this fear. ...Read more
Is any screen or shield needed to limit radiation from computer screens to prevent eye degradation?
No: Computers do not cause vision problems. Some people find that staring at a computer screen for many hours a day contributes to a condition called dry eye. You may help avoid this by reminding yourself to blink every few seconds and by looking away from the screen every few minutes. See your doctor if you have eye problems. ...Read moreSee 1 more doctor answer
Damaging genes: Inhaling or ingesting the radioactive particles that come from the explosing is also risky -- in fact, after chernobyl, most of the problems are thyroid concerns from the iodine. People in hiroshima and nagasaki had a significant rise especially in rates of leukemia, civilians exposed to tests had less cancers long-term than many had feared. ...Read more
Pkd and ionizing rad: Data are not clear on this. For sure, select mutations on either chromosome 16 or chromosome 4 lead to PKD expression. Scientists have long thought that a single mutation that affects polycystin expression leads to cyst formations. Newer data show that second or third or fourth mutations on these chromosomes affect expression of pkd. So, it is conceivable that yes ionizing rad could affect pkd ...Read more
Can digital dental xray machine malfunction and overexpose patients to radiation? Are safety mechanisms in machine/software to limit radiation levels?
No: Airplanes are not shielded from cosmic radiation. Our atmosphere protects us, but because airliners fly at high altitudes, airline crews do get a little more radiation each year than the average surface dweller. The amount of radiation per cross-country flight is small, so air travelers need not worry. ...Read moreSee 1 more doctor answer
Why Risk It?: No one really knows if cell-phone radiation causes brain cancer, alzheimers, adhd, etc. But we do know, without a doubt, that cell phones compete with healthier forms of communication; discourage exercise; expose to garbage from the media; and cause fatal accidents. Notable exceptions exist, but most kids (and many adults!) might be better off without carrying a cell phone. ...Read moreSee 1 more doctor answer
