How does nuclear decay impact half-life?
There is a simple connection between the random nature of nuclear decay and the half-life of a radionuclide. Any given atom of a radioactive element can undergo decay "any time it wants to" in the real world. This is the random nature of radioactive decay. We absolutely cannot tell whenthat one atom of whatever it is will decide to decay. The nuclear decay will happen when "it wants to" and we can only speak to the decay event of a given radionuclide by statistical means.We look at a vast number of the same kind of atoms and count the decay events. We do this over some determined interval of time, which can be shorter or longer, depending on how unstable the given radioisotope is. We'll then use our knowledge of how much we had to begin with and how many decay events we observed over out observation period to calculate how long it takes "about half" the material to decay. That's what a half-life is. It's a statistically derived span of time during which half the amount of a (sufficiently sized) sample of a specific radionuclide will decay and half will be left to undergo decay later on.

What is the decay rate of a radioactive isotope?
The decay rate of a specific radionuclide will depend on the quantity of the material in a sample. The more there is, the higher the decay rate. Decay rate for a specific isotope of a specific element is set by the nature of the radioisotope itself; it is an innate property or characteristic. Only by studying samples (specific quantities) containing large numbers of atoms of a given radioisotope, and by counting the number of decay events per unit of time, can we arrive at a characteristic called the half-life of that radioisotope.The half-life of a radionuclide is a statistically derived measure of the rate of its decay. And, to repeat, the rate of decay for a given radionuclide, is a natural characteristic of that radionuclide. It's the number of decays per unit of time that an observer can expect to count for a given sized sample of the material. Use the links below to gather more information.

Can a pet scan detect rheumatoid arthritis?
Yes.A PET Scan (or Positron Emission Tomography) Is a way of finding the most active areas in the body. the parts of the body that require the most energy use the most sugar, also referred to glucose). A PET scan uses a special material that imitates the sugar, and this is taken up by the cells in the area of activity. This material called a tracer has a small radioactive component attached to it. The images created as a result of PET scans are based on the detection of radiation from the emission of positrons (positively charged electrons) from the radioactive tracer. The subsequent images created are used to evaluate a variety of diseases, with the most common use being whole body imaging of cancer. Rheumatoid arthritis will be seen in a pet scan, However a pet scan will not tell you that it is RA that you are looking at. It will tell you that there is an area of high activity. At this stage the only way to be sure that you have RA is by recognising the symptoms and monitoring inflammation and any specific damage that may be done to various joints. through imaging such as Xray.
How is the use of radioactive decay in absolute dating similar to how you use a clock?
The ticking of a clock is constant, occurring at a steady rhythm/frequency. While the decay of radioactive elements cannot be determined at a particular point in time, they do decay at a fairly steady rate over time. This allows you to statistically determine the rate at which a mass of radioactive material will steadily decay. So, the decay rate is steady, predictable, and follows a sort of rhythm over time just like the ticking of a clock.

Can I use my printer to Scan Photo's?
Yes, just place the phote on the printer and use scan it.
What kind of beams does a CAT scan use?
CAT or CT scanning can be any of a number of different scan technologies, as CAT stands for Computed Axial Tomography and says nothing about the beams used. In common use, however, CT and CAT scans typically use X-rays, and those that use more exotic techniques are named by the technique they use (PET and NMR scans, for instance).

How does a pet scan employ elementary particles?
Elementary particles are defined by current physics as quarks, leptons and gauge bosons. A PET (positron emission tomography) scan uses positrons (antiparticles of electrons, which are a type of lepton) to generate a picture of the tissue in question. First, a radioactive isotope that decays by β+ decay (e.g. C11, N13, O15, F18) is incorporated in a organic compound that will localize to the desired tissue. When the compound arrives at the tissue, it can then under go decay and emit a positron. This positron will annihilate with the first electron it encounters, converting both their masses to energy. This energy is expressed as two gamma photons travelling in directly opposite directions so as to conserve momentum. These gamma photons are detected by the PET scanner and when a large number of the atoms are decaying, the computer can use the relative time differential (nanoseconds) between the arrival of the two photons to calculate the position of its origin and render a 3D image of the tissue.
