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.
How much of a radio active parent isotope remains after one half life has pass?
Half the original amount.
Determining the amount of radioisotope remaining at a given time?
If you know the 'half-life' of that isotope, call that period of time ' L ',call the beginning amount ' B ', and call the amount of time that haspassed since the beginning ' T '.The amount that remains at time ' T ' is(B) divided by (2T/L).
Is it false that dinosaur footprints are original remains?
Yes, it is false that dinosaur footprints are original remains.
What isotope is most commonly used in the radioactive dating of the remains of organic materials?
carbon-14

What fraction of an original sample of a radio isotope remains after 3 half-life periods?
One eighth remains.
How much of an original isotope remains at the end of a second half-life?
One quarter.
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".
How much of a radio active parent isotope remains after one half life has pass?
Half the original amount.
The half life of Rn-222 is 4 daysWhat was the original mass of a sample of this isotope remains after 21 hrs?
The half-life on 222Rn86 is 3.8235 days. A sample of this isotope will decay to 0.8533 of its original mass after 21 hours. AT = A0 2(-T/H) AT = (1) 2(-21/(24*3.8235)) AT = 0.8533

Is it false that dinosaur footprints are original remains?
Yes, it is false that dinosaur footprints are original remains.
What part of an original isotope's numberof atoms remains have two half-lifes?
After two half-lives, 25% of an isotopes original number of atoms remains. AT = A0 2 (-T/H) Where A0 is the original activity, AT is the activity after some time T, and H is the half-life in units of T, so ... A2 = A0 2 (-2/1) A2 = 0.25 A0
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.
How many Percent does the original remains of the Philippine Forest have?
20 percent of the original remains of the Philippine forest
