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.
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 percentage of radioactive nuclei left after 3 half lives have passed?
12.5%
Where does the element 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.
Do reactors produce plutonium?
Yes, nuclear fission reactors produce plutonium. 92238U + 01N --> 92239U (Uranium-238 + Neutron = Uranium-239) 92239U --> 93239Np + e- + v-e (Uranium-239 beta decays to Neptunium-239) 93239Np --> 94239 Pu + e- + v-e (Neptunium-239 beta decays to plutonium-239)
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 is the original organism decays leaving an imprint and an empty space?
Mold
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.
What happens to the amount of nitrogen14 as the carbon14 decays?
Remains the same
When elements such as uranium and plutonium decay do they form different elements chemical reactions or larger compounds?
When an element "decays", it forms a different element. This is the definition of "decay" when referring to radioactive elements.
How long will it take for 2G of tritium to decay into 2Mg?
Tritium is an isotope of Hydrogen. It has one proton and two neutrons. It decays into Helium or He. It takes 12 1/2 years for half of the original amount to decay into helium. It does not decay into magnesium. So the answer to your original question is forever.
