What is the significance of a half life of a radioisotope?
It tells what fraction of a radioactive sample remains after a certain length of time.
What is the uses for technetium pentafluoride?
Technetium pentafluoride is used in nuclear medicine for labeling compounds for imaging purposes, particularly in radioisotope scans. It can also be used in research laboratories for studying technetium chemistry and its properties.
What type of radiation is emitted by the radioactive technetium?
Technetium primarily emits gamma radiation, which is a type of electromagnetic radiation with high energy and penetrating power. Additionally, technetium-99m, a common radioisotope of technetium used in medical imaging, emits low-energy gamma radiation suitable for imaging purposes.
What is a half-line of a radioisotope if a 50-g sample becomes 25g after 18 days?
A half-life of a radioisotope is the time required for half of a sample to decay. In this case, a 50-g sample becoming 25 g after 18 days indicates that the half-life of the radioisotope is 18 days, as the sample has decreased to half its original amount in that time.
What does the half-life a radioisotope indicate?
The rate of decay for a radioactive sample
What does a half life of a radioisotope indicate?
The rate of decay for a radioactive sample
How much of a sample of radioisotope remains after one half-life?
One-half of the original amount. That's precisely the definition of "half-life".
What is the half lie of a radioisotope?
The half-life of a radioisotope is the time it takes for half of the radioactive nuclei in a sample to decay. It is a characteristic property of each radioisotope and determines the rate at which the isotopes decay.
How is technetium obtained now?
The metal technetium has no stable isotopes. It is synthesized in the physics lab by lowering a molybdenum sample into an operating nuclear reactor. The molybdenum is bathed in the nuetron flux, and neutron capture will occur and transmute the molybdenum into technetium. The sample is then withdrawn and put into a shielded casket to make it available for use. A link is provided to the Wikipedia article on technetium.
What is half life of a radioisotope if a g sample becomes g after 16 hours?
16 hours.
What does the half life tell about a radioisotope?
How long it takes for half of a sample to decay to another form.
What is the half-life of a radioisotope if a 40g sample becomes 10g after 20 minutes'?
The half-life of the radioisotope is 20 minutes. This means that in 20 minutes, half of the original sample (20g) remains. Therefore, if a 40g sample becomes 10g after 20 minutes, it has undergone 1 half-life.
