DeLaRosa supports SB3645 to prolong Illinois radiation regulatory oversight

Rep. Margaret A. DeLaRosa (D-42nd) voted Yes in support of SB3645, which aims to extend Illinois’ radiation protection authority, during the 104th General Assembly on May 31, 2026, according to the Illinois House; the bill secured unanimous approval in the House, 111-0.

The official bill summary reads: "REGULATORY SUNSET-RADIATION."

The analysis below is based on the formal bill wording and may include interpretations intended to clarify key aspects.

Fundamentally, this legislation alters the Illinois Regulatory Sunset Act to lift the planned 2027 repeal of the Radiation Protection Act of 1990, assigning a new sunset date of Jan. 1, 2037. Other professional licensing, insurance, and regulatory laws remain on track for repeal in 2027 as previously scheduled. The measure appears designed to extend state oversight of radiation protection for another 10 years. Upon passage, the act becomes active without delay.

The procedural note for SB3645 reads: 'Third Reading - Short Debate - Passed'.

DeLaRosa earned a Bachelor of Science degree from DePaul University.

DeLaRosa, a Democrat, began serving in the Illinois State House in 2025, representing the 42nd District after succeeding former state Rep. Terra Costa Howard.

Illinois legislation undergoes a multi-stage process, beginning with legislative introduction, continuing through committee review, debates on the chamber floor, and votes in both legislative bodies prior to reaching the governor for action. The Illinois General Assembly follows a biennial calendar; thousands of legislative proposals are filed each term, but only select measures reach final enactment.
