I'll take a wild guess and say 6.25mg. if that's not right I too would like to know how to compute. I had a dose today but don't know the amount they infused.

After one day, which is equivalent to 24 hours, half of the technetium-99 would have decayed. This means only 50mg of the original 100mg sample would still be present in the patient's body.

Technetium-99 has a half life of 2.111x105 years.

There is also an isotope called technitium-99m, which has a half life of 6.01 hours.

What is the stable isotope that is formed by the breakdown of a radioactive isotope?

The stable isotope formed by the breakdown of a radioactive isotope is called a daughter isotope. This process is known as radioactive decay, where a radioactive isotope transforms into a stable daughter isotope through the emission of particles or energy.


Mass number of actinium?

Unable to answer without knowing the specific isotope. However I will assume you mean actinium-227 as it is the only isotope with a halflife longer than a few days.227 protons and neutrons each composed of 3 quarks, total 681 quarks89 electronsThis gives a total of either 316 electrons, protons, and neutrons or 770 electrons and quarks. However this does not count the undeterminable number of virtual photons, muons, and gluons being exchanged by those electrons, protons, neutrons, and quarks to couple the electromagnetic, weak, and strong forces between them.


What is a antonym for isotope?

The antonym for isotope is non-isotope. An isotope refers to atoms of the same element with different numbers of neutrons, whereas non-isotope would refer to atoms of the same element having the same number of neutrons.


What is the stable isotope produced by radioactive decay is called?

The stable isotope produced by radioactive decay is called a daughter isotope.


What the number of neutrons in boron?

The number of neutrons in a boron atom varies depending on the isotope. The most common isotope of boron, Boron-10, has 5 neutrons. Another isotope, Boron-11, has 6 neutrons.

How do scientists use the halflife of radioactive isotopes to date rocks and fossils?

The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.
