What is the half life of radioisotope?
Half life is the time taken for approximately half of the available nuclei in a sample of radioactive material to decay into something else. It's a characteristic of the isotope, for example, the half life of the isotope of iodine, I131 is 8.08 days. Half lives can vary from fractions of a second to thousands of years.
What are five uses for plutonium?
Applications of plutonium: - explosive in nuclear weapons - nuclear fuel in nuclear power reactors - the isotope 238Pu is used as energy source in spacecrafts or other applications (radioisotope thermoelectric generators) - neutron generator, as Pu-Be source
Isotope A has half-life of seconds and isotope B has a half-life of millions of years which isotope is more radioactive?
Isotope A
What is meant by the half-life of a radioactive nuclide?
A half-life is the time it takes for half the original quantity of a given radioisotope to decay. If we are given a sample of one kind of radioactive material, the time it takes for half of it to undergo radioactive decay is the half-life of that radioisotope. It's a statistically derived figure, but scientists have arrived at some very accurate figures to denote the half-life of different radioactive isotopes.The half-life of an unstable material is a constant which is characteristic of exponential decay. This follows because at any time in the decay process the number of disintegrations per second is proportional to the number of atoms of the isotope present, and this is generally unaffected by any physical influence on the material.The half life of a radioactive isotope (radioisotope) is the amount of time required before half of the original mass of the isotope has decayed. For example, the radioisotope Uranium-238 i has a half-life of 4.46 billion years, therefore, if you have 100g of uranium-238 today in 4.46 billion years you will only have 50g.Radioactive substances undergoes decaying process by emitting alpha and beta particles from its nuclei of its own atoms. The time required to desintegrate half of the amount of a radioactive substance is its half life.
What does the half life of a radioisotope represent?
It tells what fraction of a radioactive sample remains after a certain length of time.
What describes radioisotope?
An isotope of an element that is radioactive
What describes a radioisotope?
An isotope of an element that is radioactive
What happens to a radioisotope when it undergoes decay?
This isotope is transformed in another isotope of another element.
What is a radioisotope in chem?
Radioactive isotopes.
What do you call an element with unstable nucleus?
Radioactive isotope, or radioisotope.
What best describes a radioisotope?
its nucleus is unstable
Why does decay chain for radioisotope U-238 eventually stop at lead?
The isotope of lead formed is stable. No other isotope in that decay chain is.
What is An unstable isotope is called what?
It isn't really an ELEMENT that is unstable, but an ISOTOPE. That means that in general, for the same element, some atoms will decay, and some will not - the difference being the number of neutrons in the nucleus.
Does the half-life of a radioisotope give?
The half life is the time when 50 % of the atoms of an isotope disintegrate.
Does a radioisotope of gold occur naturally?
No, gold has only one naturally occurring isotope and it is non-radioactive.
What fraction of the radioisotope remains in the body after one day?
If an isotope is absorbed into the body, the fraction that remains after one day depends on the radiological half-life of the isotope and the biological half-life (basically how fast the element can be eliminated from the body) of the element that the isotope represents.
What is a radioisopes?
A radioisotope is a radioactive isotope. When radioisotopes decay, they spontaneously emit particles and radiation. Radioisotopes are commonly used in scientific research and medicine.
