How many decays per second is in a curie?
Curie: A unit of radioactivity equal to 3.7 � 10^10 Disintegrations (decays) per second.
What particle is emitted when Cobalt-60 decays to Nickel-60?

A sample of an unknown radioisotope exhibits 8540 decays per second After 350 minutes the number of decays has decreased to 1250 per second What is the half life?
The decay rate N at time t is N(t)=N(0) x 2^-(t/t_half), where t_half is the half life and N(0) is the decay rate at t=0. The ^ means "to the power of."You can solve this for t_half:t_half = - t / log_2(N(t)/N(0)) (log_2 means logarithm base 2)N(350 minutes)=1250, N(0)=8540. The rest is just finding a calculator to give you log_2 of 1250/8540.
What is the definition of exponential decay in algebra?
f(t) = a + b*c-t, where a, b c are constants and t is a non-negative variable, is the general form of a function describing exponential decay. t is usually a variable related to time.The value of the function starts off f(0) = a + b and decreases (decays) towards f(t) = a.In some cases, such as radio active decay or a population extinction, a is zero so the amount of radioactive material left or surviving individuals decreases to zero.
Is it possible for a function that has a horizontal asymptote to attain the value of an asymptote?
Yes. Think of a function that starts at the origin, increases rapidly at first and then decays gradually to an asymptotic value of 0. It will have attained its asymptotic value at the start. For example, the Fisher F distribution, which is often used, in statistics, to test the significance of regression coefficients. Follow the link for more on the F distribution.
What happened to the part of the plutonium that is no longer ther?
Plutonium is a radioactive element that decays over time, transforming into other elements through a series of radioactive decays. When plutonium decays, it releases energy in the form of radiation and transforms into a different element. This process continues until the plutonium is no longer present.
What is the percentage of radioactive nuclei left after 3 half lives have passed?
12.5%
Where does the plutonium come from?
Uranium 238 is bombarded by neutrons, and forms Neptunium 238. Neptunium decays to form Plutonium 238.

What is the y in 283 94 Pu 4 2 He x y Z?
It is impossible to tell. Plutonium is found as isotopes with atomic weights in the range 238 to 244. Your equation seems to involve plutonium with another 39-78 neutrons! How that decays is anyone's guess.It is impossible to tell. Plutonium is found as isotopes with atomic weights in the range 238 to 244.

What do you call a atom that decays?
An atom whose nucleus decays over time is called radioactive. Some examples of radioactive substances are uranium, plutonium, and einsteinium.
Is there radioactive plutonium?
Yes, plutonium-239 is a radioactive isotope commonly used in nuclear reactors and weapons. It decays through alpha particle emission, and its radioactivity poses significant health risks if not handled properly.
Why do you get plutonium in a nuclear power station?
In a conventional fission reactor, the fission process produces large amounts of neutrons, which bounce about inside the reactor. When they strike atoms they can do any of a number of things, including bouncing off, causing the atom to decay, causing the atom to undergo fission, and being captured by the atom and incorporated in its nucleus. The neutron capture is what causes the plutonium to be present. When a 238U atom captures a neutron, it becomes 239U, which has a half life of 23.45 minutes and decays by negative beta decay to form 239Np. This has a half life of 2.36 days and decays by negative beta decay to form 239Pu, which has a half life of a little over 24100 years. The result is that there is an appreciable amount of plutonium in the spent fuel.
What happens to the amount of nitrogen14 as the carbon14 decays?
As carbon-14 decays, it transforms into nitrogen-14 through the process of beta decay. So, the amount of nitrogen-14 increases as carbon-14 decays.
Do reactors produce plutonium?
Yes, nuclear reactors can produce plutonium as a byproduct of nuclear fission reactions. Plutonium-239 is commonly produced in reactors and can be used as fuel for nuclear reactors or for nuclear weapons. Specialized reactors, like breeder reactors, are designed to efficiently produce plutonium for fuel or other purposes.
Gamma ray sources of the radiation?
Various radioactive substances such as Plutonium and Uranium give off a combination of alpha, beta and gamma rays as the isotope decays.
It takes 5.2 minutes for a 1.000 g sample of Fr-210 to decay to 0.250 g What is the half-life of Fr-210?
The half-life of Fr-210 is 5.2 minutes. This is because half of the original sample (1.000 g) decays to 0.500 g in the first half-life and further decays to 0.250 g in the second half-life, which takes a total of 5.2 minutes.
