Major topics include health effects, exposures, and protective measures. Other educational concepts include internal radiation hazard, radon and its daughters/progeny.

The film also examines methods for reducing exposures to radiation in workplaces. Educational concepts include ionizing radiation, radiation sickness, radiation burns, other health effects, ion pairs, free radicals, penetration versus interaction, and time/distance/shielding.

Yes! To beginning science students? Of course!Topics include general properties of ionizing radiation, interaction of radiation with matter (including health effects), the origins of radiation, a simple atomic scale model for half-lives, and nuclear waste. You need some equipment such as Vernier radiation monitors, Logger Pro, and radioactive sources.These research-based materials resolve numerous student difficulties and problematic conceptions that have been identified through repeated classroom trials and interviews with students. For example, students know very little about atoms, they do not distinguish between "radioactive" and "radiation״. The course materials deal with both of these major issues along with the idea of contamination, not distinguishing ionizing from EM radiation, and failing to understand the meaning of "ionizing" in the name "ionizing radiation״.The full set of materials uses approximately 40 hours of classroom time and includes detailed descriptions of student difficulties and tactics for addressing them.The materials were created by Andy Johnson of CAMSE at Black Hills State University with help from undergraduate assistants. The goal is to enable teaching radiation to students using inquiry approaches. The materials have been under development for about six years. This is the latest version as of the summer of 2011. With the assistance of the NSF, work is continuing on this project and additional & improved materials will be available in the future. Three simulators have been developed for this project: Atom Builder for investigating the properties of atoms, Atom Invaders for investigating the interaction of radiation with single atoms or molecules, and Tracks for working out details of the interaction of alphas, beta, and gamma radiation with everyday objects that the macroscopic, cellular, and molecular size scales. http://www.merlot.org/merlot/viewMaterial.htm?id=594456 This film examines the process of radioactive decay as part of an educational unit on the health effects of ionizing radiation (radioactivity). Educational concepts include radioisotope, radioactive decay, alpha radiation, beta radiation, gamma radiation, x-radiation, decay chain, and half-life.

There are courses available in the following areas:Architecture and Planning, Engineering, Health Sciences and Technology, Humanities, Arts and Social Sciences, Management, Science, Atheltics, Physical Education and Recreation, Experimental Study Group and Special Programs. This website also contains the following features: images/graphics, links to related material,learning assignments and teacher's guide to help further understand the courses.

Provides students with opportunity to synthesize knowledge acquired in nuclear and non-nuclear subjects and apply this knowledge to practical problems of current interest in nuclear applications design. Past projects have included using a fusion reactor for transmutation of nuclear waste, design and development of a nuclear reactor for the manned mission to Mars. Meets with graduate subject 22.33. http://www.merlot.org/merlot/viewMaterial.htm?id=591336 This course is a foundational study of the effects of single and multiple interactions on neutron distributions and their applications to problems across the Nuclear Engineering department - fission, fusion, and RST. Particle simulation methods are introduced to deal with complex processes that cannot be studied only experimentally or by numerical solutions of equations. Treatment will emphasize basic concepts and understanding, as well as showing the underlying scientific connections with current research areas. http://www.merlot.org/merlot/viewMaterial.htm?id=591404 This course provides an in-depth technical and policy analysis of various options for the nuclear fuel cycle. Topics include uranium supply, enrichment fuel fabrication, in-core physics and fuel management of uranium, thorium and other fuel types, reprocessing and waste disposal. Also covered are the principles of fuel cycle economics and the applied reactor physics of both contemporary and proposed thermal and fast reactors. Nonproliferation aspects, disposal of excess weapons plutonium, and transmutation of actinides and selected fission products in spent fuel are examined. Several state-of-the-art computer programs are provided for student use in problem sets and term papers. http://www.merlot.org/merlot/viewMaterial.htm?id=591554 This course deals with structural components in nuclear power plant systems, their functional purposes, operating conditions, and mechanical-structural design requirements. It combines mechanics techniques with models of material behavior to determine adequacy of component design. Considerations include mechanical loading, brittle fracture, in-elastic behavior, elevated temperatures, neutron irradiation, and seismic effects.
