    • Monthly Radiation Safety Training is available at the (East Baltimore Campuse) JHMI downtown. These classes are available to all members of the Johns Hopkins Community. Attending these training lectures will indicate that you have completed the minimum Radiation Safety Training to use radioactive materials. Please contact our Homewood or East Baltimore campus office for more information.
    • Also, these courses are offered at the Homewood Campus every fall.

Homewood Campus

In order to ensure that the use of ionizing radiation for research at this university does not result in the unnecessary exposure to individuals and to the general public, Johns Hopkins University maintains a Radiation Safety Office on the Homewood Campus. This office is also responsible for monitoring and enforcing compliance with all applicable state and federal regulations concerning the use and handling of radionuclides and other sources of ionizing radiation, including analytical x-ray machines and electron microscopes.
