Which female inventor spent a lifetime studying radioactivity?
Polish physicist Marie Curie, discoverer of both radium and polonium, spent much of her adult life studying the radioactive elements and the x-rays they emitted. Not only was radiation the bulk of her life's work, it was the cause of her demise as well: Curie died of Leukemia caused by repeated, unprotected exposure to radiation in 1934.
Was Marie curie blind?
Marie Curie was "almost blind" when she died in 1934. Her death was from Leukemia brought on by her lifetime of exposure to radioactive elements. Pierre Curie was not blind, as far as I know, and was killed in 1906 when he was run over whilst crossing a road and suffered a fractured skull. His body was so weak, again as a result of exposure to radiation, that it could fight to stay alive.
Where do red blood cells spend most of their lifetime?
They spend their lifetime mostly in blood stream, transporting oxygen.
How the lifetime of stars depend on their mass?
The larger a star the shorter the lifetime because, larger stars burn out more quickly.

What is the safe level of nuclear radiation?
The answer to the question depends more on what you consider safe than anything else. The real question is whether any given exposure has sufficient benefit to outweigh the amount of damage that might be done. In some cases, we need to do things that expose us to ionizing radiation in order to stay alive and be healthy, and the amount of exposure is so small that the chance of problems coming from it is to small to worry about. Any exposure to ionizing radiation can cause medical problems. There is no lower limit, beyond which it is absolutely safe. This includes not only nuclear radiation but other ionizing radiation, such as ultraviolet light, as well. For example, exposure to sunlight can cause skin cancer, and the chance of getting cancer is directly related to the amount of sunlight. The only way to eliminate the chance of getting cancer from sunlight absolutely is to eliminate the exposure absolutely. The problem with this is that we need some exposure to sunlight to ensure good health, so eliminating it is more dangerous than limited exposure. Similarly, exposure to beta or gamma radiation can cause medical problems, and the only way to eliminate these problems being caused by such radiation is to eliminate the exposure. The problem with eliminating the exposure is that it cannot be done. About one out of every 9000 potassium atoms is radioactive, and will give off gamma or beta radiation. But potassium is also a requirement for life, as a chemical, and eliminating it would quickly cause a person to sicken and die. We put smoke detectors in our houses, because early detection of fires saves lives. The smoke detectors usually contain radioactive substances, but the increased threat from them is negligible compared to the increased threat from fire without them. We are exposed to nuclear radiation in medical practice that is intended to benefit our health and extend our lives. So to answer the question precisely, we would have to say that there is no absolutely safe level of radiation greater than none at all. What we have to do is assess each potential source of radiation and ask whether the risk of exposure is small enough that the actual exposure is overall beneficial. Since the question of whether something is safe cannot be answered without some subjective evaluation, I will tell you my own belief. I believe that we are all subjected to as much radiation as we need, and probably more, already, assuming we use sunscreen or cover ourselves well. If any further exposure is to be done, there should be some very good, specific reason for it. So, the safe limit for further exposure is zero.
Does radiation levels on earth increase during solar storms?
Not appreciably, or at least, not at sea level. Flight crews flying at 42,000 feet on polar routes (for example, Los Angeles to London or New York to Tokyo) _ARE_ at risk of increased radiation exposure. And some commercial airline flights have been cancelled for this reason! The Earth's atmosphere protects us against most solar radiation, but at high altitude, you are above 3/4 of the atmosphere. For most airline crews, it's only a minor increase in the lifetime radiation exposure risk. But solar storms can increase the risk. And on polar routes, the Earth's magnetic field offers less protection than in temperate latitudes. When all three combine, the risk of radiation-induced cancers can get up to the "Measurable" level.
How much nuclear radiation is considered safe for humans?
From MIT: Adult: 5,000 Millirems per year The current federal occupational limit of exposure per year for an adult (the limit for a worker using radiation) is "as low as reasonably achievable; however, not to exceed 5,000 millirems" above the 300+ millirems of natural sources of radiation and any medical radiation. Radiation workers wear badges made of photographic film which indicate the exposure to radiation. Readings typically are taken monthly. A federal advisory committee recommends that the lifetime exposure be limited to a person's age multiplied by 1,000 millirems (example: for a 65-year-old person, 65,000 millirems). Minor: 500 Millirems The maximum permissible exposure for a person under 18 working with radiation is one-tenth the adult limit or not to exceed 500 millirems per year above the 300+ millirems of natural sources, plus medical radiation. This was established in 1957 and reviewed as recently as 1990. Fetus: 500 Millirems Or 50 Per Month (New Rule Jan. 1, 1994) New federal regulations went into effect New Year's Day, establishing for the first time an exposure limit for the embryo or fetus of a pregnant woman exposed to radiation at work. The limit for the gestation period is 500 millirems, with a recommendation that the exposure of a fetus be no more than 50 millirems per month. Weight Variables Like alcohol intoxication levels, levels of exposure to radioactivity (due to radioactivity deposited in the body) depend on a person's weight. A diagnostic tracer of one microcurie of radioactive calcium 45, given orally, would result in an exposure of 3.7 millirems for a 100-pound person, and half of that, 1.85 millirems, for a 200-pound person. Therapeutic Radiation Therapeutic radiation treatment that is delivered by administering radioactive material via the mouth or by injection usually results in high, very localized doses to a small part of the body, which absorbs most of the radioactivity. The radioactivity concentrates and remains in the target organ (for example, the thyroid) for a longer period of time than does the radioactivity that is distributed to the rest of the body. The radiation exposure for other parts of the body is a function of the amount of radioactivity per pound and the time the radioactivity is present in the tissue. As well if you are looking for ways to reduce your risk of radiation there are certain foods and supplements that you can take that can greatly reduce your risk, squidoo.com/radiation-alert-inspector-measure has more answers
What is the maximum amount of radiation a human body can tolerate?
100 milliSieverts is the smallest radiation dose clearly linked to cancer. 1 Sievert is the smallest radiation dose required to induce radiation sickness. The average person absorbs 250 millirems over a lifetime.

What is the lifetime of artificial sateliites?
It depends on the satellite. If it runs out of fuel, it can't maintain its proper orbit. Radiation eventually degrades the electronics. None of them last forever.
What form of radiation poses the most serious risk to human health?
Gamma radiation cannot be effectively shielded, it can pass through many feet of heavily leaded concrete with little attenuation. However it is often possible to get far from the gamma emitting material, which is the best way to protect oneself.Alpha radiation while easily completely blocked by one sheet of paper or your skin, ingestion of particles of alpha emitting materials will cause significant tissue damage and likely cancer, as the tiny particles usually lodge inside tissues and cannot be removed, producing a continuous lifetime exposure of those tissues.Take your pick as to which is worse.
I have had over 60 chest x rays at least 50 in a 3 month span a few hand and hip plus my entire spine also had a total of 7 CT scan plus 2 upper GIs and 1 Hida Scan is that too much?
Simply put, no it isn't too much. Diagnostic x-ray and NM exposure is very minimal and obviously if you've had that many tests done in a short time, there were valid reasons for the tests, so the benefit of the tests outweighed the risk of harm from radiation exposure. Exposure accumulates over your lifetime. If you continued receiving exposure at this rate years to come, you may start to see symptoms. The harm done by 1 chest x-ray is equivalent to the harm done by smoking 1 cigarette.
Chances of getting cancer from 3 CT scans?
Radiation exposure from a CT scan is similar to, though higher than, that of a conventional x ray.Although severe contrast reactions are rare, they are a risk of many CT procedures. There is also a small risk of renal failure in high-risk patients

How do you win trust of your partner?
Trust can be on different levels my friend. If you are referring to trusting your spouse then TRUST THEM WITH ALL YOUR MIGHT. They wil in turn trust you gradually and it will last a lifetime. Or create a scene where you can make her/him believe that you deserve their trust.
