Dr. Lightner was formerly an Office Director within the Department of Energy's Environmental Management program. He has extensive experience in the development of nuclear and fossil energy systems as well as in energy related environmental restoration and waste management.
This course covers fundamental aspects of radioactive substances in the environment; remediation processes for these substances; and their eventual storage, processing, and disposal. It provides a basic understanding of radioactivity and its effect on humans and their environment, and the techniques for their remediation and disposal. Topics include radioactivity, the nucleoids, interaction of radiation with matter, shielding, dosimetry, biological effects, protection standards, sources of environmental radiation, risk evaluation, fate and transport analysis, cleanup standards, legal requirements, cleanup technologies, waste disposal, and case studies.
Provide a technical understanding of the fundamental aspects of radioactive substances in the environment, remediation processes for these substances, and their eventual storage, processing, and disposal.

Student Assessment Criteria
|Individual assignments and quizzes||30%|
|Issue paper and presentation||20%|
|Small Group activities||15%|
|Large Group activity||5%|
Individual assignments require the performance of scoping calculations to solve quantitative problems or performance of well-focused research. Issue paper requires development of a cuurent issue related to radioactive material in the environment. A written paper is submitted and an oral presentation is made to the class. Small Group activities include cooperative dicussions and working of related problems. Discussions include issues raised in the course material as well as from student submitted press "clips" of contemporary issues. A Large Group activity will evaluate current events or issues and will culminate with a submittal for class discussion.
Computer and Technical Requirements
Working knowledge of computer spread sheet, presentation and browser programs is assumed. Possession of a working USB headset is required for participation in weekly Office Hours.
Modules consist of presentations by the instructor, reading assignments, class discussions, group problem solving and some contemporary audio/visual materials. Students are expected to activly participate each week, to complete weekly assignments, to collaborate in group activities, to submit a written issue paper, and to make an on-line presentation on their selected issue topic.
Textbook information for this course is available online through the MBS Direct Virtual Bookstore.
There are notes for this course.
Final Words from the Instructor
The presence of radioactive materials in the environment presents a unique set of challanges to the environmental professional. Control of wastes becomes increasingly vital as more extensive use is made of nuclear medicine and nuclear power. The malevolent uses of the substances in nuclear bombs and dirty bombs and the potential for accidents must be understood to permit effective protection of humans and the environment in the event of radioactive releases.
