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 and t=1hour© BrainMass Inc. brainmass.com March 4, 2021, 11:25 pm ad1c9bdddf
Hello and thank you for posting your question to Brainmass!
The solution is attached below in two files. the files are identical in content, only differ in format. The first is in MS Word format, while the other is in Adobe pdf format. Therefore you can choose the format that is most suitable to you.
The equation that governs the radiactive decay is:
Where A is the activity (in units of disintegration per unit time), is the reaction rate and N is the number of active nuclei.
The solution to this separable differential equation is:
Where N0 is the initial number of active ...
The expert examines nuclear decay for radioactive sources. How many radioactive nuclei are present are determined.
