Why do you choose isotopes with medium long half-lives as emitter in radiotheraphy?
Mainly for two reasons:to reduce as far as possible the radioactivity and hence reduce the radioactivity passive health effects; as the element radioactivity is inversely proportional to its the half live.To reduce as far possible the loss of the radioactive element through its radioactive decay during storage for non use.
What role do enzymes have the cell?
reduce the amount of energy required for activation
What can be used to reduce the energy required to start a chemical reaction?
That is the function of a catalyst.
How does enzymes catalyze reactions?
they reduce the activation energy required for the reaction to occur
How a enzymes catalyze a chemical reaction?
they reduce the activation energy required for the reaction to occur
Ways to reduce radioactive waste?
you can't
What will happened to the ke if its velocity is reduced by 12 times?
Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.
Why wouldn't freezing radioactive waste reduce radiation?
Radiations are independent from temperature.
How do you reduce rheumatoid factor?
no one knows.
How must the voltage across a resistor change to reduce the current in the resistor by a factor of 3?
The voltage must reduce by the same factor - that is Ohm's law.
Where is greatest common factor use?
The greatest common factor is used to reduce fractions.
Which of the following compounds can be administered to reduce the absorption of radiation that targets the thyroid?
Potassium iodide can be administered to reduce the absorption of radiation that targets the thyroid. It works by saturating the thyroid with non-radioactive iodine, thereby reducing the uptake of radioactive iodine.
What is the minimum weld required on weldolets have welded a CS as the main run pipe is of less thickness?
To be fully welded out plus a fillet of @ 6mm to reduce the stress concentration factor at the bottom toe.
What does reduce by a factor x means?
It means to divide by x. For example, if I were to reduce 4 by a factor of x, I would get 4/x.If I reduced x by a factor of x, I would get x/x, which is equal to 1.
What do you use greatest common factor for?
To reduce fractions
How do you reduce fractions if one number is odd?
The parity (odd or even) of a number has no relevance in reducing fractions. What is required is to find the highest common factor between the numerator and denominator. Clearly, if the numerator and denominator are bot even then 2 is a common factor and so it must be possible to reduce the fraction. The highest common factor or even a common factor may not be so obvious when both numerator and denominator are odd.For example, 21/91 = (3*7)/(13*7) = 3/13
What radioactive decay processes do not reduce the atomic number of a nuclide?
Isomeric transition and internal conversion are examples of radioactive decay processes that do not reduce the atomic number of a nuclide. These processes involve the reorganization of the nucleus rather than changing the number of protons in the atom.
