NUCLEAR SCIENCE
Renamed from Atomic Energy
- Do the following:
- Describe the biological effects and hazards of radiation to
humankind, the environment, and wildlife. Explain the difference
between deterministic and stochastic effects. In your explanation,
discuss the nature and magnitude of radiation risks to humans from
nuclear power, medical radiation, and background radiation. Explain
the measures required by law to minimize these risks.
- Describe the radiation hazard symbol and explain where it should
be used. Tell why and how people must use radiation or radioactive
materials carefully.
- Tell the meaning of the following: ALARA, alpha particle, atom,
background radiation, beta particle, contamination, curie and becquerel,
gamma ray, half-life, ionization, quark, isotope, neutron, nuclear
energy, nuclear reactor, particle accelerator, rad and gray, radiation,
radioactivity, radon, rem and sievert, and X-ray.
- Choose five individuals important to the field of atomic energy and
nuclear science and explain each person's contribution.
- Choose an element from the periodic table. Construct 3-D models for
the atoms of three isotopes of this element, showing neutrons, protons,
and electrons. Use the three models to explain the difference between
atomic number and mass number. Then do the following:
- Make a drawing showing how nuclear fission happens, labeling all
details. Draw another picture showing how a chain reaction could be
started and how it could be stopped.
- Explain what is meant by a "critical mass."
- Do any THREE of the following:
- Build an electroscope. Show how it works. Place a radiation source
inside and explain any difference seen.
- Build a model of a reactor. Show the fuel, control rods,
shielding, moderator, and any cooling material. Explain how a reactor
could be used to change nuclear energy into electrical energy or make
things radioactive.
- Using a radiation survey meter and a radioactive source, show how
the measurements per minute change as the source gets closer to or
farther from the radiation detector. Place three different kinds of
materials between the source and the detector, then explain any
differences in the measurements per minute. Explain how time,
distance, and shielding can reduce the radiation dose.
- Obtain a sample of irradiated and non-irradiated foods. Prepare
the two foods and compare their taste and texture. Store the leftovers
in separate containers and under the same conditions. For a period of
14 days, observe their rate of decomposition or spoilage, and describe
the differences you see on days 5, 10, and 14.
- Describe how radon is detected in homes. Discuss the steps taken
for the long-term and short-term test methods, how to interpret the
results, and explain when each type of test should be used. Explain
the health concern related to radon gas and tell what steps can be
taken to reduce radon in buildings.
- Visit a place where X-ray is used. Draw a floor plan of the room
in which it is used. Show where the unit, the unit operator, and the
patient would be when X-ray is used. Explain the precautions taken
when X-ray is used and the importance of those precautions.
- Make a cloud chamber. Show how it can be used to see the tracks
caused by radiation. Explain what is happening.
- Visit a place where radioisotopes are being used. Using a drawing,
explain how and why they are used.
- Obtain samples of irradiated seeds. Plant them. Plant a group of
non-irradiated seeds of the same kind. Grow both groups. List any
differences you observe during a 30-day period. Discuss with your
counselor what irradiation does to seeds.
- Visit an accelerator (research lab) or university where people
study the properties of the nucleus. After your visit, discuss what
you have learned with your counselor.
- Do ONE of the following:
- Give an example of each of the following in relation to how energy
from an atom can be used: nuclear medicine, environmental
applications, industrial applications, space exploration, and
radiation therapy. For each example, explain the application and its
significance to nuclear science.
- Find out how many nuclear power plants exist in the United States.
Locate the one nearest your home. Find out what percentage of
electricity in the United States is generated by nuclear power plants,
by coal, and by gas.
- Identify three particle accelerators in the United States. For
each accelerator, describe three experiments that have been done or
are in progress. Name three particle accelerators in the United States
and describe the type of experiments each accelerator is designed to
perform.'
- Find out about three career opportunities in nuclear science that
interest you. Pick one and find out the education, training, and
experience required for this profession and discuss this with your
counselor. Tell why this profession interests you.
