Cutnell & Johnson PHYSICS 6/e
Chapter Thirty-Two: Ionizing Radiation, Nuclear Energy and Elementary Particles

Biological Effects of Ionizing Radiation (Radiation Basics)

excerpt from the Radioactive Materials Safety Class at the Princeton University Initial Radiation Safety Training (for Open-Source Radioisotope Users) at

This site contains a brief overview presentation of damage mechanisms, tissue sensitivity, effects, exposure, risks and prenatal exposures. See also

Marie Curie and the Science of Radioactivity

An online exhibit from the American Institute of Physics celebrating the life and work of Curie.

Perhaps the most remarkable scientific woman of the 19th century, Curie opened up the science of radioactivity, discovering two elements and winning two Nobel Prizes (her daughter won a third Nobel). This site was written with material from biographer Naomi Pasachoff.

The CPEP Particle Adventure

The Contempory Education Physics Project (CPEP) is a non-profit organization of teachers, educators, and physicists around the world. They have produced a number of excellent materials including award-winning charts and websites for teaching physics and cosmology.

This lavish site contains interactive tutorials, animationsand classroom materials describing the standard model of particle physicsand elementary particles.

Plasma Physics & Fusion; The Universe Adventure

The Contempory Education Physics Project (CPEP) also has produced charts, lesson plmaterials and extensive sites describing both Plasma Physics & Fusion, and an up-to-date cosmological site, The Universe Adventure.

The Universe Adventure includes a discussion of Dark Matter.

The Mechanical Universe and Beyond

Program 51: From Atoms to Quarks. A thirty-minute on-demand streamed physics lecture / animated presentation hosted by Professor David Goodstein of the California Institute of Technology as part of the Annenberg / CPB series The Mechanical Universe and Beyond.

This site requires cable modem (384K) or better speed connection to the internet and free registration with Annenberg / CPB.

Virtual Tokamak

Internet Plasma Physics Education eXperience (IPPEX), Princeton University Plasma Physics Laboratory (PPPL).

To show the principles of magnetically confined fusion, the site has a virtual fusion reactor, called the 'Virtual Tokamak.' Try the Plasma Drift Applet to get a feel for how magnetic fields are used to contain a plasma in a tokamak.
