Keeping Radioactive Sources Safe and Secure - Preventing Loss, Theft and Misuse

<strong>Basic Ionizing Radiation Symbol:</strong> To signify the presence of ionizing radiation and to identify sources and devices that emit ionizing radiation.

<strong>Ionizing-Radiation Warning - Supplementary Symbol:</strong> To warn of the presence of a dangerous level of ionizing radiation from a high-level sealed radioactive source.
