Exploring the Table of Isotopes
This is a periodic database. each element contains expected information such as atomic number symbol and more. But also details like the discoverer, meaning of the name and color . Other features on this web page include isotope pattern calculator and element percentage calculator. Don't miss the animated glossary of nuclear science terms
ABCs of Nuclear Science
ABCs of Nuclear Science, and Particle Adventure are parts of a larger project sponsored by the Contemporary Physics Education Project (CPEP). After exploring radioactivity and the pages which follow, check out the rest of the site. You'll find particle physics presented in a way which makes it fascinating-- even if you are not a physicist.
"Science Fair Report: Detection of Solar X-Ray Flares with a Geiger Counter" by Vicki Rae Mims.
Science PROBE ; v1, n2 , p32-34,120, Apr 1991.
Described is a science fair project in which M- and X-class x-ray flares
on the surface of the earth were detected using a Geiger counter.
Background information, the problem, hypothesis, a list of needed
materials, the procedure, observations, conclusions, and a critique are
"Teaching about Radioactivity and Ionising Radiation: An Alternative Approach" by Robin Millar; and Others.
Physics Education; v25, n6, p338-42, Nov 1990.
Children's ideas about radiation and radioactivity are reviewed and several common areas of misunderstanding are identified. An approach to teaching the topic at the secondary school level which seeks to specifically address known difficulties is outlined.
"Radioactivity: A Natural Phenomenon." by C. Ronneau.
Journal of Chemical Education; v67, n9, p736-37, Sep 1990.
Discussed is misinformation people have on the subject of radiation. The importance of comparing artificial source levels of radiation to natural levels is emphasized. Measurements of radioactivity, its consequences, and comparisons between the risks induced by radiation in the environment and from artificial sources are included.
"Growth and Decay: An Experiment Demonstrating Radioactivity Relationships and Chelate Solvent Extraction Separations." by D. M. Downey and Others. Journal of Chemical Education; v61, n3, p259-61, Mar 1984.
The separation of lead and bismuth by chelate solvent extraction is of interest because of the simplicity which the use of radiotracers allows in its demonstration. Theoretical background information, procedures, materials needed, and typical results are provided for an experiment involving the extraction.
