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.
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.
Technetium-99 has a half life of 211,000 years.
That's called a daughter isotope, or a daughter product. (The original isotope that decayed is the parent isotope.)
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.
It is an isotope of a neutral atom.
This is the isotope plutonium-238: 23894Pu.
Any isotope with 24 protons is chromium; therefore, the requested isotope is 54Cr.
Yes, but it has a halflife of only 0.86 seconds.
no, halflife is a constant for each isotope's decay process.
many. one example is lead-214 with a halflife of 26.8 minutes.

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.
Uranim-234 is a rare natural isotope of uranium - the abundance is 0,0054 %.This isotope ha 92 protons, 142 neutrons and an atomic mass of 234,040 952 1(20).His halflife is 245 500 years.
Isotopes can be injected into a person in order to make MRI / x-ray scans more accurate. When they inject an isotope into you (like say an iodine isotope) they can see exactly where that isotope goes throughout your body (through the blood vessels if injected or through your gastrointestinal tract if swallowed).
The isotope iodine-131.
No, halflife is a bulk statistical property of a quantity of an isotope of an element.Individual nuclei do not have halflives, instead they have a probability of decaying at the current moment of time.
You think probably at 8 neutrons; in this case the extremely unstable isotope is 10He. Atomic mass: 10,0524; Halflife: 2,7.10-21 seconds
The half life of uranium is not one day. For an isotope with the half life or one day, after 3 days: the quantity remained is 12,5 %.
