Radiation Safety Manual


Radioactive materials and radiation machines are used by Baylor University faculty, staff, and students. These materials are highly regulated by local, state, and federal entities. This manual ensures the compliant and safe use of all such materials and machines as required by law.


This manual defines the acceptable use and possession of all radioactive materials or radiation machines emitting ionizing radiation by all Baylor University faculty, staff, and students.


It is the responsibility of each individual department at Baylor University to ensure that its students, faculty and staff use materials and machines which emit ionizing radiation in a legal, safe and compliant manner. The University Radiation Safety Officer (RSO) shall act as an advisory point of contact and the Department of Environmental Health & Safety (EHS) shall act as an advisory and support organization. The Department of EHS and University RSO will manage the application of this manual in support of the Radiation Safety Policy (Ionizing Radiation).
