The equations that are nuclear reactions are as follows:
- superscript 185 subscript 79 upper Au right arrow superscript 181 subscript 77
- superscript 210 subscript 84 upper Po right arrow superscript 206 subscript 82 upper Pb plus superscript 4 subscript 2 upper He.
<h3>What is nuclear reaction?</h3>
A nuclear reaction is a reaction that involves the fission of an atomic nucleus, or the fusion of one or more atomic nuclei and/or subatomic particles in which the number of protons and/or neutrons in a nucleus changes.
The products of a nuclear reaction may contain a different element or a different isotope of the same element.
Therefore, the equations that are nuclear reactions are as follows:
- superscript 185 subscript 79 upper Au right arrow superscript 181 subscript 77
- superscript 210 subscript 84 upper Po right arrow superscript 206 subscript 82 upper Pb plus superscript 4 subscript 2 upper He.

Answer:
The half-life is 
Explanation:
From the question we are told that
The sample is 90 Y
The first activity is 
per minute
The second activity is 
per minute
The duration from 1:00 p.m. on December 3, 2006 to 2:15 p.m. on December 17, 2006 is
Converting to minutes we have
The first order rate constant for this disintegrations can be mathematically represented as
Where 
is the rate constant
Substituting values
![ln [\frac{5.8 * 10^{3}}{2.2 *10^{5}} ] = - \lambda * 20235](https://tex.z-dn.net/?f=ln%20%5B%5Cfrac%7B5.8%20%2A%2010%5E%7B3%7D%7D%7B2.2%20%2A10%5E%7B5%7D%7D%20%5D%20%3D%20-%20%20%5Clambda%20%2A%2020235)
So
The half life is mathematically represented as
So
