I need very good information about Radium and it's uses in our life.?

This is made for people with rading problems.  The last name of the guy who invented it was Kurzweil.  You can do the rest of the research.

go look at the link I provided.  it has lots of good info.

Rutherfordium, Rhenium, Rhodium, Ruthenium...ahh Rubies...take your pick.

Use google. Sometimes you can dig up a lot of useful info.

http://spontaneousmaterials.com/Papers/REPMW90.pdf\n\nAn excellent article on the myths and usages of lanthanides

Write the word 'radioactivity' in www.google.com.Then collect watever information u need.

go to www.google.com them write periodic table and than go to images and you'll see

Radium half life is 1602 years...\nso if we may consider it to be 1600 years than after 1600 years you will find approx. half of the radium left in the container = 0.5 kg\nafter 4800 years = 3 x half life ... in the container there remain about 1/8 of the original mass,  = 0.125 kg\n\nbut if you want to calculate exactly there is the radioactive decay law, see http://en.wikipedia.org/wiki/Half_life

There are a variety of sources. If it's a physical constant, I'd suggest the CRC Handbook of Chemistry and Physics or Langer's Book of Chemistry. You might also try the chemical literature through scifinder, if you are at a university that has a subscription.

Use Google scholar:\nhttp://scholar.google.com/scholar?q=calcium%20toxicity%20in%20kidney%20cells&hl=en&lr=\n\nAlso here is the tutorial on how to search Entrez Pub-Med\nhttp://www.nlm.nih.gov/bsd/disted/pubmed.html\nIts actually pretty complicated to find what you want thats why I left the tutorial page.\n\nIm sure you can find ALOT of published papers on your subject. Its not an uncommon subject.\n\nGood Luck!

look up the periodic table...duh

Three basic concepts apply to all types of ionizing radiation. When we develop regulations or standards that limit how much radiation a person can receive in a particular situation, we consider how these concepts might affect a person's exposure.  \n\nTime \nThe amount of radiation exposure increases and decreases with the time people spend near the source of radiation. \n\nIn general, we think of the exposure time as how long a person is near radioactive material. It's easy to understand how to minimize the time for external (direct) exposure. Gamma and x-rays are the primary concern for external exposure.\n\nHowever, if radioactive material gets inside your body, you can't move away from it. You have to wait until it decays or until your body can eliminate it. When this happens, the biological half-life of the radionuclide controls the time of exposure. Biological half-life is the amount of time it takes the body to eliminate one half of the radionuclide initially present. Alpha and beta particles are the main concern for internal exposure. \n\nDistance   \nThe farther away people are from a radiation source, the less their exposure. \nHow close to a source of radiation can you be without getting a high exposure? It depends on the energy of the radiation and the size (or activity) of the source. Distance is a prime concern when dealing with gamma rays, because they can travel long distances. Alpha and beta particles don't have enough energy to travel very far. \nAs a rule, if you double the distance, you reduce the exposure by a factor of four.  Halving the distance, increases the exposure by a factor of four.\n\nThe greater the shielding around a radiation source, the smaller the exposure. \n\nShielding simply means having something that will absorb radiation between you and the source of the radiation (but using another person to absorb the radiation doesn't count as shielding). The amount of shielding required to protect against different kinds of radiation depends on how much energy they have. \n\n \n(Alpha)\n\n A thin piece of light material, such as paper, or even the dead cells in the outer layer of human skin provides adequate shielding because alpha particles can't penetrate it. However, living tissue inside body, offers no protection against inhaled or ingested alpha emitters.\n    \n \n(Beta)\n\n Additional covering, for example heavy clothing, is necessary to protect against beta-emitters. Some beta particles can penetrate and burn the skin.\n   \n \n(Gamma) \n Thick, dense shielding, such as lead, is necessary to protect against gamma rays. The higher the energy of the gamma ray, the thicker the lead must be. X-rays pose a similar challenge, so x-ray technicians often give patients receiving medical or dental X-rays a lead apron to cover other parts of their body. \n\nSo in short the lead or other materials absorb the radiation vs. it being absorbed by your body.

radioactivity is the spontaneous emission of alpha beta or gamma rays from a radioactive substance to attain stability.\nthey can be used as tracers to know the path of ne reaction\nsome of them can be used to treat cancer like co-60. and uranium is already used in nuclear reactors for generating electricity.

not much\nsomething else decays into radium, or is recombinant

For this kind of information, wikipedia is the ideal start. Additionally, visit a library and check any chemical dictionary or encyclopedia. While the language may appear strange, the information you want will be recognizable with some patience.
