Exposure To Radiation (Overview)

Exposure to low levels of ionizing radiation from X-rays, CT scans and radioactive materials increases the chance of various cancers and leukemias later in life. Microwaves and other radio waves, such as the transmissions from cell phones, do not have this effect.

What would symtoms be from exposure to radiation fallout?

Fatigue: Would be most common, diarrhea (sometimes bloody), and weight loss can all be signs of acute exposure to high levels of radiation. Not a big problem unless world war iii starts... ...Read more

What amount of exposure to radiation is considered too much?

What amount of exposure to radiation is considered too much?

Any you don't need: Radiation exposure is guided by the principle of ALARA- As Low As Reasonably Achievable. So, any imaging or treatment involving radiation exposure should be considered in light of risk:benfit ratios. If you don't need a scan, don't have a scan. Same goes for treatment, but with that said radiation is a very useful tool in the management of a number of conditions. ...Read more

Which is best way to minimize your child's exposure to radiation?

Which is best way to minimize your child's exposure to radiation?

Avoid midday sun: The biggest radiation source is the midday sun. When the sun is at it's highest intensity, it's a good time to cover up, go inside, find shade, etc. Also, imaging can cause notable radiation exposure. Not so much from xrays but from ct scans. Especially for those with small children, be judicious with head ct scans. If they bump their heads, observation for 6 hours is just as effective. ...Read more

Can you tell me how is a person's exposure to radiation routinely checked?

Can you tell me how is a person's exposure to radiation routinely checked?

No routine check: People at risk for radiation exposure usually wear badges. If you were not wearing a badge, you can test your white blood cells for radiation damage. This is not cheap or routine though. ...Read more

What would long and short term effects be from exposure to radiation fallout?

Very different: Very high ( > 100 rads), short-term doses of radiation have been known to cause early effects, such as diarrhea, skin burns, cataracts, and even death. It is suspected that radiation exposure may be linked to the potential for genetic effects in children of exposed parents. Longer term, lower level exposure is known to cause many kinds of cancer, and also cataracts. ...Read more

In what way can we reduce exposure to radiation to minimize the risks of health effects?

Stay out of the sun: To minimize exposure to radiation you should stay out of the sun: Slip, slap, slop: http://ts1.mm.bing.net/th?id=HN.607994767425406449&w=250&h=105&c=7&rs=1&pid=1.7 ...Read more

Do the health effects of exposure to radiation differ for acute vs. Chronic low-level exposure?

Do the health effects of exposure to radiation differ for acute vs. Chronic low-level exposure?

Very much so: Acute exposure causes burns, destruction of bone marrow, and other tissue injuries like cataracts. Long term exposure can lead to various cancers, and amazingly, also cataracts. Both can kill! one form of chronic low-level radiation exposure is the sun, so wear sunscreen! ...Read more

Can exposure to radiation accumulate during a lifetime or does it wear off after a certain amount of time?

Can exposure to radiation accumulate during a lifetime or does it wear off after a certain amount of time?

Both: Radiation treatment plans are designed to maximally treat the tumor or target area while respecting the known tolerances of the nearby normal structures. There are generally accepts limits for most bodily organs. However, after a course of treatment there is some "forgiveness" as the tissues repair the radiation damage. So there are times when repeat treatment is both beneficial and safe. ...Read more

Do you have any exposure to radiation through microwave?

The electromagnetic : Spectrum includes visible light, radio and micro waves, infrared red, ultraviolet, x-rays and megavoltage radiation. There is heating with microwaves, ergo their ubiquitous use in your home and cafeterias, but no ionizing, which is the damaging to dna action of radiation and radiotherapy. ...Read more

Exposure to radiation is so rare, but should people have ki in their medicine cabinets?

Exposure to radiation is so rare, but should people have ki in their medicine cabinets?

No: More than likely, somebody is going to overdose or inadvertently take it, causing more complications. If there is exposure to radiation, contact poison control and follow their instructions. If there is a major radiation exposure, the ki in your cabinet will likely still need instruction before being taken. ...Read more

Could exposure to radiation cause cancer 30 years later?

Could exposure to radiation cause cancer 30 years later?

Yes, unfortunately: For example, patients with hodkin's lymphoma who received radiation therapy to the chest wall can have increased risk to develop breast cancer due to the radiation-years after the radiation itself. Patient who received radiation for acne or head & neck cancer- can develop thyroid cancer- many years after radiation therapy. ...Read more

Which professions would likely have the highest occupational exposure to radiation per year?

Uranium miners: And workers are #1 and #2. Airplane crews are #3. But no, safeguards put in place over the last 100 years have limited exposure to far below cancer-causing levels. Only an employer who was in blatant violation of international standards for safety (as established by iaea) would submit a worker to unsafe levels. Sadly, such employers do exist in the third world. ...Read more

Exposure to radiation while driving under power lines; does that cause cancer?

Exposure to radiation while driving under power lines; does that cause cancer?

No way.: The dose is so small that even people living under power lines don't get more cancer. You get more radiation flying in a plane or having an x-ray. Even going on the roof of a tall building gives you more. Forget about it. ...Read more

Does bone scan process involve any exposure to radiation as in x ray?

Does bone scan process involve any exposure to radiation as in x ray?

Yes: Both x-ray an isotope for bone scan produce ionizing irradiation. Exposure from isotope of bone scan in adult is about 6 msv. This is similar to some ct scans.The only imaging methods not involving irradiation are ultrasound and magnetic resonance imaging mri. Information from each test is not the same. ...Read more

Are radiologists likely to get cancer because of their exposure to radiation?

Are radiologists likely to get cancer because of their exposure to radiation?

In the early: days of radiology, little was known about the long term effects of radiation, and many xray workers and doctors ended up with cancers. Nowadays, exposure is minimized by safety equipment and improved technology. Radiologist xray exposure is monitored on a regular basis with badges and other detectors. ...Read more
