DISCLAIMER The following is a staff memorandum or other working document prepared for the members of the Advisory Committee on Human Radiation Experiments. It should not be construed as representing the final conclusions of fact or interpretation of the issues. All staff memoranda are subject to revision based on further information and analysis. For conclusions and recommendations of the Advisory Committee, readers are advised to consult the Final Report to be published in 1995. TAB H þþþDRAFTþFOR DISCUSSION PURPOSESþþþ MEMORANDUM TO: Members of the Advisory Committee on Human Radiation Experiments FROM: Advisory Committee Staff DATE: November 9, 1994 RE: Green Run Case Study The Green Run is the name given to the December 1949 release of 28,000 curies of radioactive gases from the Hanford plant, apparently to test methods of detecting nuclear weapons production and testing in foreign countries. This Tab presents the Green Run case study in a way that parallels as much as possible the presentation of the plutonium injection case study (Briefing Book 7, Tab G). It begins with four memos that provide some background discussion of the ethics of intentional environmental releases of radioactivity. There follows a memo on the available facts and gaps in knowledge about the Green Run itself, and an analytical piece for discussion that addresses the ethics issues of the Green Run. (See below.) PART I - Background Memoranda on the Ethics of Intentional Releases IA - Discussion Points on the Ethics of Intentional Releases This memo discusses the ethical issues that arise in the release of radioactive materials into the environment. The discussion parallels the issues raised in the plutonium injection case study. 1B - Current Environmental Regulations and Oversight This memo summarizes the environmental regulations and oversight mechanisms that apply to intentional releases of radioactivity, paying particular attention to the effects of secrecy and national security. 1C - How Well Do Current Regulations Meet Ethical Concerns? This memo attempts to identify the correspondence between these regulations and the underlying environmental ethics issues. 1D - Dose Reconstruction Dose reconstruction is the method for estimating actual harm to individuals. We attach a fact sheet on the subject from the Technical Steering Panel of the Hanford Environmental Dose Reconstruction Project. Dr. John Till, former chair of this panel, will be giving a presentation to the Committee. PART 2 - Memorandum: The Facts and Unknowns of the Green Run This memo provides an overview of the facts of the Green Run. It also addresses the questions of fact that we cannot yet answer, but may be addressed in classified documents. PART 3 - Memorandum: An Analysis of the Green Run This memo discusses the Green Run from the point of view of both ethics and current environmental regulations. It asks whether the Green Run should have been permitted and whether it could have occurred under current regulations.
