The use and disposal of radioactive materials and radiation-emitting equipment in activities such as teaching, research, or other services is regulated by federal and state statutes. Control and monitoring of activities involving radioactive materials and radiation-emitting equipment as well as disposal of wastes is the responsibility of the Radiation Safety Officer (RSO) in the Environmental Health and Safety Office working under the aegis of the Vice President for Research and Technology Transfer and the Radiation Safety Committee (RSC). All personnel (faculty, staff, students, guests) using such materials must comply with all applicable regulations. Authorization to use such materials is only available from the RSO and the RSC and must be obtained prior to acquiring materials or equipment. Information describing the procedures for obtaining authorization, purchase, use, and disposal of materials and equipment is available from the Environmental Health and Safety Office. RSO access to laboratories and other facilities to perform inspections is a necessary part of compliance with regulations governing purchase, storage, use, and disposal of radioactive materials and radiation-emitting equipment.
