No research with nuclear, biological, or chemical agents using volunteers will be undertaken without the consent of the Secretary of the Army. Any duty as a volunteer performed during the employee's regularly scheduled tour of duty will be considered as constructive duty for which straight time rates are payable. Time spent in connection with an experiment outside the employee's regularly scheduled tour will be considered as voluntary overtime for which no payment may be made nor compensatory time granted. The employee will be so informed before acceptance of his volunteer services. Claims submitted to the Bureau of Employees' Compensation, U.S. Department of Labor, because of disability or death resulting from an employee's voluntary participation in experiments, will include a citation to title 10, United States Code, section 4503 as the Department of the Army authority for the use of such volunteer services.
All questions concerning hours of duty, pay.
Heads of major commands and other agencies will issue necessary implementing instructions to subordinate units. Copies of implementing instructions will be furnished to the Chief of Research and Development.
