This fraction is 12,5 %.
1/32
N = N0 X e ^ (-kb X t) where: NO the initial amount = 100 kb is the constant = 0.056 t is the time = 50 I get 6.1 after 50 years.
In reality, as the atoms gets decayed it gives out radiations such as alpha, beta and Gama. Alpha is a helium nucleus which is massive and beta is electron but fast moving and Gama is an electromagnetic radiation. So as the atom decays then its mass is likely to be reduced. Rutherford's radioactive law deals with the number of atoms undecayed present at an instant 't' given in the form N = No e-lambda t Here No is the total atoms present both decayed and undecayed in a sample. N is the number undecayed present lambda - the decay constant t - the time elapsed
No. DOE has set the limit at 10,000 dpm/100cm2 by wipe sample.
Half of the original sample of a radio isotope remains after a half-life period. After two half-life periods, one-fourth of the radio isotope remains.
1.5% remains after 43.2 seconds.
The fraction that remains is 1/8.
It tells what fraction of a radioactive sample remains after a certain length of time.
An eighth remains.
1/8 of the original amount remains.
It is 1/8 .
One eighth remains.

The fraction or ratio of a sample possessing a certain trait is called a Proportion.
