Required to be done before Class: tba
Can be done before or after class: tba
Required to be done after class: tba Merit Badge
Requirements:
- 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.
- 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.
