Me i beg you i really need gamma, beta and alpha radiation are all alike because: they all have the same mass they all have the same charge they all can be emitted from the nucleus of an atom they all have the same energy alpha, beta and gamma radiation all show different levels of penetration because: they have different energies they have different frequencies they have different wavelengths of all of these reasons when an atom releases an alpha particle: the atom s mass number decreases by 4 the atom s mass number decreases by 2 the atom s mass

The correct answer is measurement in Ci/Bq, the amount of radioactive materials released into the environment, and number of disintegrations of radioactive atoms in a radioactive material over a period of time. I hope this helps.

Nuclear medicine is a branchhh hof medicine which uses radioactive materials in diagnosis and therapy. radioactive substances are administered to patients and the radiation emitted is measured. iodine-131 which has a half-life of k days is a substance that is used to diagnose and treat cancers of thhhe thyroid gland. the graph below is an exponential decay for a dose(d) or iodine-131 given to a patient as a function in time in days. the graph shows the iodine remaining in body (% of dose) from 0-100 starting at 100. and the bottom of the graph

I'll just do it from the top just in case you didn't do something right

so,half life formula

A=P(1/2)^(t/k) where k is the half life and P is initial amount (or percent)

so, initial is 100
P=100

and, when t=24, A=12.5
so

solve for k

given
P=100
t=24
A=12.5
so

12.5=100(1/2)^(24/k)
divide both sides by 100
(12.5/100)=(1/2)^(24/k)
take ln of both sides
ln(12/5.100)=ln((1/2)^(24/k))
properties of logarithms
ln(12/5.100)=(24/k)ln(1/2)
times both sides by k
kln(12/5.100)=24ln(1/2)
divide both sides by ln(12.5/100)
k=(24ln(1/2))/(ln(12.5/1000))
use your calculator
k=8
exactly
so

$A=100(\frac{1}{2})^{\frac{t}{8}}$ is da equation

c.
solving for t when A=5

so
A=5

$5=100(\frac{1}{2})^{\frac{t}{8}}$
solve for t
divide oth sides by 100
$\frac{5}{100}=(\frac{1}{2})^{\frac{t}{8}}$
take ln of both sides
$ln(\frac{5}{100})=ln((\frac{1}{2})^{\frac{t}{8}})$
property of logarithm
$ln(\frac{5}{100})=(\frac{t}{8})ln(\frac{1}{2})$
times both sides by 8 and divide both sides by ln(1/2)
$\frac{8ln\frac{5}{100}}{ln\frac{1}{2}} =t$
t≈34.5754
so to the tenth
34.6 days

What does the half-life of a radioisotope represent? O A. It represents the amount of energy produced by the isotope s radioactive decay. O B. It represents the time it takes for half of the material to decay to a daughter element. O c. It represents the type of radiation that is being emitted by the radioactive material. D. It represents how long the radioactive material has been in existence in that form.
