Radioactive decay single parent to daughter product
See attached file for the formula.
Q1)
If a radioactive parent isotope decays to produce a stable daughter isotope, what will be the daughter to parent ratio (D/P) after 9 halflives? You should give your answer as a single number.
Q2)
What is the product of the beta minus decay shown below? Fill in the atomic number, mass number and symbol for the resulting nucleus
Finding amount of stable Daughter product from radioactive decay of parent isotope....methodology
We do not know the decay constant Lamdain the Question so we need to effectively eliminate it
So we need to determine and answer the Question What is half life in terms of decay constant?
Consider a radioactive isotope source with decay constant lamda
Also consider that the isotope starts with (No) atoms at time t = 0
The number of atoms at any time t is defined by the decay law namely
N(t) = No.exp(lamda*t) (1)
Now the time taken for a radioactive isotope to decay to half its mass (N/2) is given by solving (1) with N(t) replaced by N/2 and t the time replaced by the half life T(1/2)
Thus to ...
Solution Summary
Analysing the decay of a single radioactive parent nuclide to a single daughter product nuclide and determining the ration of Daughter to Parent (D/P) after 9 half lifes of the parent species.
The second part of the question shows how to look at beta  decay of Carbon 14 with the emmision of an electron and antineutrino and how to determine the resultant Nucleus, its mass number, atomic munber and species type
The equation for radioactivedecay is: N(t) = Noekt, where No is the initial number of radioactive atoms, N(t) is the number of radioactive atoms left after a time t, and k is the decay constant. The halflife of carbon 14 is about 5730 years.
Radioactive carbon dating makes the assumption that living things absorb carbon 14
A radioactivedecay series that begins with 237/93 Np ends with formation of the stable isotope 209/83 Bi. How many alpha particle emissions and how many beta particle emissions are involved in the sequence of radioactivedecay?
I need some help in determining the halflife:
1. A radioactive source has a half life of 74 days and an activity of 370 MBq. what was the activity 30 days ago?
2. A radioactive source has a half life of 60 days. what is the relative activity after one week?
3. An 11 Ci Ir 192 source is recieved on August 20. Regulator
For Uranium235, Thorium232 and Samarium147:
1) How long is its halflife?
2) How long will it take for there to be 25 percent of original radioactiveproduct left?
3) What material is it best used for?
4) What are the disadvantages and advantages of using this element for dating?
5) Describe the process of decay it u
Question: The naturally occurring isotopes of potassium are:
39 K (abundance 93.10%)
40 k (abundance 0.0118%)
41 k (abundance 6.88%)
40K is radioactive and decays by Beta decay with a halflife of 1.29 multiplied by 10`9 years.
a) How many protons and neutrons does each of the three isotopes of potassium have?
b)
Pu241 is produced from neutron absorption by Pu240 (which is produced by neutron absorption by Pu239). Calculate the fractional ingrowth of Am241 from Pu241 (i.e. number ratio Am241/Pu241) from time = 0 to 200 years. Pu241 is the parent and Am241 is the daughter.
Three radioactive sources each have activities of 1.0 micro Curies (Ci) at t=0. Their half lives are 1 sec, 1 hour and 1 day respectively
a.) how many radioactive nuclei are present at each source when t=0
b.)how many nuclei of each source decay between t=0 and t=1sec
c.)how many nuclei of each source decay between t=0

Examples of the binomial and Poisson distributions are all around us.
 Identify a reallife example or application of either the binomial or poisson distribution.
 Specify how the conditions for that distribution are met.
 Suggest reasonable values for n and p (binomial) or mu (poisson) for your example.
