does a  person exposed to radiation has no chance of survival?

it depends on what kind of radiation he is exposed to..well even sunlight is radiation and we all live ...X rays that are used for imaging are also radiation and no-one dies fron getting x rayed...so it is the type and amount that a person is exposed to..if the radiation can denature the proteins that make up our body and change the DNA that is responsible for all cell divisions then we may not live otherwise our very life is proof that we can survive radiation

We don't do body counts. Independent estimates range from 75.000 to 150,000. That doesn't account for the one who will die in the future from their injuries or the estimated half million who will die within 10 years from radiation poisoning.

There is a huge difference between ionizing and non-ionizing radiation.  RF radiation is non-ionizing and unless you have such high levels that you could be burned by it, there is no inherent danger - just keep below the ANSI levels.  There have been tons of epidemiological tests which show that there is no causality to cancer.  Remember that light is another source of non-ionizing radiation and people don't seem too concerned about being 'bombarded' by it.

Irradiated foods are safe.  They are not radioactive (at least not due to the irradiation process) any more than you are after exposure to x-rays (although THEY can be harmful).  The radiation kills bacteria in the food.  \n\nIf irradiation did increase genetic variability it would probably be good for the human race, because, due to advances in medicine, the race is stagnating (genetically, that is) because harmful mutations and deadly diseases no longer always limit life, so the propensity for such mutations and diseases is passed on by reproduction.

Yes, depending on how far along the cancer is when it is found, and when treatment starts.  Not everybody survives this one.

My heart goes out to you and your sister.  People DO survive lung cancer.  Taking chemo is a tough decision to make, it can destroy the quality time you may have left IF  hers is NOT in a curable stage.  Most doctors WILL give honest answers IF the patients ASK:  Is my cancer curable?  What are my chances of surviving with surgery only?  What are my chances of surviving WITH and WITHOUT chemo? Or  WITH and WITHOUT radiation?\nShe might need you to go with her to ask these questions, (I encourage you to WRITE DOWN your questions, and let the doctor SEE you have a list of questions...) for the support, and so you can reaffirm what she was told.   An amazing number of people are unable to clearly remember and process the info they are given when the disease is life-threatening.  If you were with her, and later she can't quite recall the information, you could gentley help her work through the answers.\n Encourage her to get second opinions if she feels she needs more information.  Not EVERY form of cancer, not EVERY patient is good candidate for chemo.  Chemo can often cause more life ravaging consequences than the cancer itself.  I can understand her hesitancy in NOT jumping into chemotherapy.  Please do not let anyone make her feel like a "quitter" or guilty for NOT choosing chemo IF HERS IS not curable.  Perhaps she will choose to focus her fight on maintaining her dignity, independence, and quality of life as long as she is able to- IF HERS IS NOT IN A CURABLE STAGE.  \nSometimes radiation and other cancer treatments are given as a palliative measure, meaning it will not CURE the cancer, but hopefully if can keep the tumors from causing decreasing function of of organs in the chest, or from causing increased pain.\nIf it IS treatable, and if it IS a stage of cancer that will repond to surgery, chemo, and radiation, etc, it may make it easier for her to bear the treatments if she knows she DOES have a chance to survive.  She has a right to that information about her own particular stage of cancer before she makes the choice. Take care, I wish you both well.

Someone working with helium is not being exposed to any more Alpha radiation than someone who doesn't work with helium.  It is when someone is working with something with a much higher atomic weight that they get exposed to the radiation from the decay of the larger nucleus into smaller particles that include the Alpha particle.

Radiation therapy tends to kill the stem cells in the bone marrow, which can result in a weakned immune system and aplastic anemia (basically, your body doesn't produce enough red blood cells) since both red blood cells and immune cells are produced from stem cells in the bone marrow.  In some cases, this requires a bone marrow transplant, which, when sucessful, typically has minimal long-term consequences.\n\nRadiation can also weaken the bone itself.

Yes but the receiving person cannot develop cancer from it.\nCancer is a condition where the cells in the human body become confused as to what their job is and as a result they start attacking the body laying waste to it.  Since her white blood cells are healthy(I'm assuming), they will recognize the strange cells as something that is not supposed to be there and kill them.\n\nIf the woman got cancer later on, it would have nothing to do with you.\n\nYou can relax.

Everything in this universe emanates radiation, including your body. The only exception is objects that are already at absolute zero.

It doesn't help at all, no. Plants are not radiation shields, not that computers emit any dangerous radiation anyway!

No. They have a very low wattage of radiation, far below what would be harmful.

The Astronauts were exposed to the radiation not only \nas a consequence of pasing through the Van Allen Belt \nbut also being exposed to the radiation from the Sun.\nThe amount of radiation would have certainly been lethal had they spent more time in space than they did.\nBut for the up to eight days the Astronauts spent\nout of the protective cocoon of Earth's natural \nradiation shield the astronauts were not in any real danger. On the other hand,the danger of a sudden major solar flare-up resulting in radiation exposure so intense to have killed the astronauts in space was  always a possibility.

my mother in law just went through this and just had radiation too.  her doctor said the cancer was in a fairly small area, and the radiation was just as effective and wouldn't give her the side effects of chemo, but if it came back or they found it had spread, she would have to have the chemo then.  good luck to your sister!

No as cancers go it is relatively rare

What kind of treatment?  That is not a word!  Do you mean radiation?  Need to ask your doctor.  This is not something a layperson on Yahoo Answers is likely to know the answer to...especially if your question is not clear.  CALL YOUR DOCTOR.  If you are already receiving medical treatment, why in the world would you ask strangers for medical advice instead of asking your doctor?

Keep in mind, I'm not a nuclear Engineer or a nuclear specialist.  I haven't studied nuclear physics since college 10 years ago.\n\nRadiation in any form is dangerous.  It is just whether the benfits outweigh the potential ill side effects.\n\nRadiation is actually caused by the decay of a radiactive subtance.  Radiation takes three forms, alpha, beta, and gamma radiation.\n\nAlpha radiation consists of 2 protons and 2 neutrons.  Alpha particles are slow and can not penetrate much.  This type of radiation can be stopped by something as thin as a sheet of paper or clothing.\n\nBeta radiation is actually an electron.  While beta radiation penetrates more than alpha radiation, it is still weak.  It can be stopped by thin metals, such as a sheet of foil.\nGamma radiation is the radiation that is very deadly.  Gamma radiation is actually a wave and not a particle.  It can only be stopped by thick layers of dirt, concrete, or lead.\n\nDuring nuclear fallout, a person doesn’t become radioactive per se.  What happens is the dust and particles collected on their clothing emits radiation.  You may have heard of radiation suits.  Radiation suits do not stop radiation, rather their purpose is to prevent radioactive particles from becoming embedded in hair, skin, or clothing.  Once the person gets away from the contaminated area, they wash the suit, disrobe, and (my guess) run like hell.\n\nRadiation sickness is caused by an overdose of radiation.  The danger of radiation is that it kills the cells of any living thing that it strikes.  This can be beneficial in a medical setting like when a radiation beam is used to kill cancer cells in a patient.  However, when a person is exposed to uncontrolled radiation over a prolonged period of time, many of the cells in their body are killed.  Just like anything else, dead things begin to decay and rot.  Radiation sickness is essentially the body becoming poisoned and weak from the loss of cells and decaying cells in their body.\n\nWithout adequate protection during radiation fallout, radioactive particles become ingested, inhaled, and embedded on the skin.  \n\nI hope this helps a little
