Gamma Rays (Definition)

This is light of extremely short wavelengths typically produced either among the stars / in cosmic rays or by radioactive element decay. Gamma rays form the background of normal radiation in which we all live; it is substantially greater than the exposure we get from imaging scans or should get from ...Read more

What is too much radiation?

What is too much radiation?

Radiation: There is no specific answer to this question with respect to using radiation for medical purposes. General radiation safety revolves around the 'ALARA' principle. ALARA is an acronym formed from the phrase “As Low as Reasonably Achievable.” The phrase refers to the principle of keeping radiation doses to the patient as low as can be achieved under the circumstances. ...Read more

Why is radiation bad for us?

Why is radiation bad for us?

Mutations: When ionizing radiation goes through the body it causes electrons to be ejected from atoms, leaving behind free radicals which can damage DNA. DNA damage can cause cell death, mutations from inaccurate repair, or be repaired back to normal. Inaccurately repaired DNA (mutations) can cause a cell to act wildly or grow into a cancer. ...Read more

Does beam radiation stay in body?

No.: Once the radiation machine (called a linear accelerator) is turned off, there is no radiation in the body. You are not radioactive. ...Read more

How harmful is background radiation?

Harmless: Did you feel it? It just hit you. And those flying planes and living at high altitude (like denver) have higher exposure and no higher frequencies of any cancer. ...Read more

How can I get my radiation levels tested?

How can I get my radiation levels tested?

Lab: Workers around emitted radiation ( xray, xrt, etc.) are monitored regularly with dosimeters and those with exposure to particulate radiation ( nuclear industry) are additionally monitored with radiation counters and body fluid samples. Internal contamination is sometimes measured in special chambers if screening tests are abnormal. If you have concerns you should talk to your doc. ...Read more

What does to much radiation do to the body?

What does to much radiation do to the body?

Chronic exposure: Stochastic effects are associated with long-term, low-level (chronic) exposure to radiation. Increased exposure makes health effects more likely to occur, but do not influence type or severity of the effect.Damage occurring at the cellular or molecular level, can be disruptive, permitting the uncontrolled growth of cells cancer. R;adiation can cause changes in dna, mutations.Genetic effects. ...Read more

How much radiation could cause health problems?

Variable: At high radiation doses, a human cell can be damaged so severely that it will die. At lower doses, the cell can repair the damage and survive. If the repair is faulty, however, the cell could give incorrect information to the new cells it produces. High doses of radiation received in a short period of time result in effects that are noticeable soon after exposure. ...Read more

How do you remove radiation from someone's body?

Your body: doesn't become radioactive after being exposed to radiation. Theoretical damage from radiation occurs from direct damage or from mutagenic effects, but once the source of radiation is turned off, there is no more radiation. There are some nuclear medicine tests where radioactive substances are injected or ingested, but typically these decay relatively quickly or are eliminated via urine etc... ...Read more

How do I avoid the radiation effect from mobiles?

How do I avoid the radiation effect from mobiles?

Radiofrequency: Cell phones are a source of radio frequency radiation, however at this time, there is lack of significant evidence to show that cell phones can lead to an increased risk to formation of brain tumors. Many of the studies already done have biases or data that is not conclusive. To avoid this radiation, do not use a cell phone. ...Read more

Is it possible to get radiation injections for pain?

Let's Clarify: Flouroscopy, x-ray radiation , is used to guide needle placement for a variety of interventional pain procedures that may relieve pain. Radiation therapy is used in some cancer patients to directly irradiate the tumor and relieve pain. Each particular situation should be assessed by a board certified pain specialist. ...Read more

Are planes shielded from damaging radiation from space?

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 more

Could radiation be transmitted to you through airborne?

Depends: Radiation refers to particles like electrons going through space being emanated from a radioactive source. So, in that sense that are through the air, but it is unlike viruses transmitting through the air when someone coughs or sneezes. We are subject to radiation from space all the time and then from earthbound sources. ...Read more

What happens if I was exposed to radiation for 2 years?

Depends on dose: Your body is able to repair damage caused by radiation to a certain degree. Radiation, toxic chemicals, and certain metabolic processes cause oxidative damage to your body's tissues. Tissues that divide more frequently (like intestinal epithelium and hair follicle cells) are more susceptible to oxidative damage, which is why toxic chemical & radiation exposures cause certain effects. See your MD. ...Read more

How do radiation that transmission by PC effect our healty?

PC radiation?: I am not aware that personal computers have any radiation to affect your health. But too much work in front of computer may have other side effects, depends on your posture in front of computer, and what sites you navigate to.Pay attention to posture and quality information in dealing with computers. ...Read more

How fast does radiation dissipate after it has been released?

How fast does radiation dissipate after it has been released?

The 7-10 rule: The danger of radiation from fallout decreases with time. With each factor-of-seven increase in time (7 hours after the fallout hits, 49 hours afterwards, 343 hours (2 weeks) afterwards, etc... ) the radiation is reduced by a factor of 10. ...Read more

Please describe a good diet for someone undergoing radiation?

Please describe a good diet for someone undergoing radiation?

See below: The recommendations are that you eat well with lots of fruits/vegetables and limited red meat/processed foods. If you are neutropenic you should avoid some fresh fruits/vegetables for that time period when your white cells are low; your oncologist will have info on what specifically to avoid for that time period. Otherwise, just a good balanced diet without any specific recommendation. ...Read more
