Calcalate the half life of cesium- 135 if seven- eighths of a sample decay in 6 times ten to the sixth years?
you know that the half life is 32.2 min and th fration is 3/4 what you do first is that you subtract 1 from 3/4 so you get 1/4 next you know that 1/2 is amout of sample remaining after on whole life so 1/2 multiplied by 1/2 is 1/4 so there are 2 half lifes so than you multiply 2 by 32.2 and you get 64.4 minutes and that is you answers hope that helps.....
What else can I help you with?
How much cesium would remain from a 10 g sample after 6 years?
After 6 years, approximately 5 grams of cesium-137 would remain from a 10 g sample due to its half-life of around 30 years. This decay is exponential, with about half of the original sample decaying every 30 years.
What is the parent radioisotope if a beta decay produces barium 137?
Same mass, atomic number one lower - Cs - caesium
How much cesium half-life 2 years would remain from a 10 g sample after 4 years?
2 1/2g
What is the name for the length of time of a decay process?
The length of time for a decay process to occur is called the half-life. It represents the time it takes for half of the radioactive isotopes in a sample to decay.
Determine the amount of time it takes for three fourths of a radioactive sample of an isotope of bromine to decay the half-life of the isotope is 16.5 hours?
The half-life of the isotope is 16.5 hours, so it takes 16.5 hours for half of the sample to decay. To find the time it takes for three fourths of the sample to decay, you would calculate 2 half-lives (2 x 16.5 hours) as three fourths is equal to 1.5 times the original amount (1 + 0.5). Therefore, it would take 33 hours for three fourths of the sample to decay.
What is the half life of cesium 137?
The half-life of cesium-137 is about 30 years. This means that it takes 30 years for half of a sample of cesium-137 to decay into a more stable element.
What is the Half-life of Cesium-124?
I have heard varying numbers from 33. something seconds to years.
How much cesium would remain from a 10 g sample after 4 years?
As you did not specify an isotope of cesium, I will assume you meant natural cesium. Natural cesium is not radioactive so it does not decay. There will always be the same 10 g of cesium, no matter how long you wait.
How long did it take for xenon to decay into cesium?
Most isotopes of Xenon are stable and so do not decay. The shortest lived isotope has a half life of more than 10^16 (10 quadrillion) years.
How much cesium would remain from a 10 g sample after 6 years?
After 6 years, approximately 5 grams of cesium-137 would remain from a 10 g sample due to its half-life of around 30 years. This decay is exponential, with about half of the original sample decaying every 30 years.
If 12.5 grams of the original sample of cesium-137 remained after 90.69 years what was the mass of the original sample?
To find the original mass of the cesium-137 sample, you can use the exponential decay formula: final amount = initial amount * (1/2)^(time/half-life). With the information provided, you would have: 12.5 = initial amount * (1/2)^(90.69/30.1). Solving for the initial amount gives you approximately 40 grams.

What is relative decay?
Relative decay is the process of determining the age of a sample by comparing the amount of a radioactive isotope it contains to the amount of its decay products. By measuring the ratio of remaining isotope to decay product, scientists can estimate the age of the sample based on the known decay rate of the isotope.
As the temperature of a radioactive sample increases the rate of the nuclear decay?
The rate of nuclear decay increases as the temperature of a radioactive sample increases. This is due to the increased kinetic energy of the nuclei at higher temperatures, which facilitates interactions that lead to nuclear decay.
What does the half life of a radioisotope correspond to?
The length of time required for half of a sample of radioactive material to decay
