A uranium nucleus emits an α particle. Assuming charge is conserved, the resulting nucleus must be
a. thorium
b. plutonium
c. radium
d. curium
3. A 100kg sample of Neptunium 234 (Np234) was accidentally released due to the gross
negligence of Jerf, the worst nuclear engineer ever.
A. Jerf plans to act as though nothing happened until 95% of the sample has decayed
into other elements. How long will they have to keep waffling about pretending
to do experiments? (hint: Wikipedia knows the half-life of (Np234))
B. After two weeks, Jarrison, Jerf's supervisor, notices Jerf has had a minor decrease
in productivity and decides to confront Jerf. Realizing their jig is up, Jerf decides
to eat as much as they can before Jarrison notices. Assuming they eat 5 kgs of
Np 234, how much is left for Jarrison to find?
C. Following this incident, Jarrison, along with the EPA, makes a graph detailing
the amount of Np 234 in Jerf's lab. Draw this graph and label all important events.
Do not include the amount of Np234 that Jerf ingested, as a serendipitous genetic
immunity to radiation Jerf inherited is the only reason they did not succumb to…
