SB 1121 Arizona Senate · 57th Legislature - Second Regular Session

radiation protection systems; medical procedures

SB 1121 requires Arizona hospitals, outpatient surgical centers, and other health care facilities performing radiation procedures to install a radiation protection system in procedure rooms before they can stop requiring staff to wear lead aprons. The system must provide protection equivalent to a 0.25 millimeter lead apron and include real-time radiation exposure monitoring for health professionals. Staff may still choose to wear lead aprons voluntarily even when the system is installed. This law directly affects medical facilities and health professionals conducting procedures like X-rays or fluoroscopy using ionizing radiation.

Senate Engrossed Version (03/02/2026) Chaptered Version · 3 edits
MINOR
The bill was finalized and approved by the Governor, changing the status from a pending Senate version to an enacted law. The substantive policy changes clarify that hospitals can exempt staff from wearing lead aprons if a radiation protection system is used, but this exemption is no longer absolute; officials must now assess if exposure levels are too high and require protective gear if necessary. Additionally, the definition of a 'radiation protection system' was updated to explicitly include real-time dosimetry as a required component.
Scope change
The bill's scope remains focused on hospitals performing cardiac catheterization, but the applicability of the exemption for not wearing lead aprons is now conditional on radiation safety assessments rather than just the presence of shielding equipment.
REQUIREMENT

The exemption from wearing lead aprons was modified to require a safety assessment by a radiation safety officer; if staff exposure approaches dangerous thresholds, the officer must mandate the use of lead aprons, thyroid collars, or other protective equipment.

DEFINITION

The definition of 'radiation protection system' was updated to explicitly state that the system must include real-time dosimetry to measure radiation exposure for health professionals.

TIMELINE

The document was finalized with specific dates, showing approval by the Governor on June 19, 2026, and filing with the Secretary of State on June 22, 2026.
