radiation protection systems; medical procedures

Plain English Breakdown

The official text does not define 'designated safety zone' despite amendments mentioning it; this term is removed from the explanation as no definition was provided in the final statute excerpt.

SB1121: Radiation Protection Rules for Cardiac Procedures

This law stops hospitals from requiring staff to wear lead aprons during certain heart procedures if the room has a strong radiation shield, but it requires those who skip the apron to wear real-time exposure monitors.

What This Bill Does

• Prohibits hospitals from requiring physicians and nurses to wear lead aprons during cardiac catheterization with x-rays if the room uses an approved radiation protection system that is used according to manufacturer instructions.
• Allows a hospital's safety officer to require protective gear like lead aprons or thyroid collars if staff exposure levels get too high based on the 'as low as reasonably achievable' standard.
• Requires health professionals who choose not to wear a lead apron in these rooms to wear a real-time dosimeter device.
• Defines a radiation protection system as shielding that offers at least the same safety as a 0.25 millimeter lead-equivalent apron.

Who It Names or Affects

• Hospitals performing cardiac catheterization procedures with real-time x-ray imaging
• Physicians, physician assistants, nurses, and other health professionals in these procedure rooms

Terms To Know

Cardiac catheterization

A medical procedure that uses thin tubes to treat heart problems while using x-ray imaging.

Radiation protection system

Shielding in a room designed to block radiation as well as or better than a lead apron.

Real-time dosimeter

A device that measures and shows how much radiation a person is receiving right now.

Limits and Unknowns

• The law only applies to hospitals, not outpatient surgical centers or other health care institutions.
• Hospitals must follow the manufacturer's instructions for using the radiation protection system for this rule to apply.
• The specific date when this law takes effect is listed as the general effective date in the text.

FACT SHEET FOR
S.B. 1121

radiation
protection systems; medical procedures

Purpose

Prohibits
hospitals that perform cardiac catheterization procedures involving real-time

x-ray imaging from requiring health professionals to wear lead aprons during
those procedures if the procedure room is equipped with a radiation protection
system.

Background

Health care
facilities utilize comprehensive sets of measures to prevent worker injury and
negative health effects from exposure to high radiation levels.
Control measures, including engineering
controls such as shielding with lead aprons, administrative controls such as
monitoring and access restrictions and
personal protective
equipment,
function to protect
workers by reducing the radiation dose, limiting time exposure and preventing
contamination
(
OSHA
).

Health care
personnel present in a procedure room using ionizing radiation must utilize
either protective aprons or whole-body protective barriers with a minimum
lead-equivalent thickness of 0.25 millimeters to reduce occupational radiation
exposure. Additionally,� medical personnel must wear both badge type dosimeters
and direct reading dosimeters during radiographic procedures to monitor and
document individual radiation dose and support compliance with applicable
occupational exposure limits (A.A.C.
R9-7-604

and
R9-7-1130
).

There is no anticipated fiscal impact to the state
General Fund associated with this legislation.

Provisions

1.

Prohibits a hospital

that performs cardiac
catheterization procedures involving real-time x-ray imaging from requiring
that physicians, physician assistants, nurses or other health professionals
wear lead aprons during these procedures if the procedure room is equipped with
a radiation protection system that is in use according to the manufacturer's
instructions.

2.

Allows a hospital's radiation safety officer or designee to require lead
aprons, thyroid collars or other radiation personal protection equipment if the
radiation safety officer or designee determines, according to the
as low as
reasonably achievable
standard, that staff exposures will approach
occupational dose thresholds or elevated exposure.

3.

Requires hospitals to instruct health professionals who choose not to
wear a lead apron
because the procedure room is
equipped with a radiation protection system
to wear a real-time
dosimeter to monitor radiation exposure.

4.

Specifies that health professionals are not prohibited from voluntarily choosing
to wear a lead apron during a procedure involving real-time x-ray imaging even
if the procedure room is equipped with a radiation protection system.

5.

Defines
radiation protection system
as a shielding system that is
designed to protect against scatter or direct ionizing radiation exposure, that
provides protection equal to or greater than the shielding effectiveness of a
0.25 millimeter lead-equivalent apron.

6.

Becomes effective on the general effective date.

Amendments Adopted by
Committee

1.

Requires health care institutions to instruct health professionals who
choose not to wear a lead apron to wear a real-time dosimeter.

2.

Makes conforming changes.

Amendments Adopted by
Committee of the Whole

1.

Removes outpatient surgical centers and other health care institutions from
the lead apron enforcement requirement.

2.

Applies the exception to the lead apron requirement, for hospitals that
use a radiation protection system, to cardiac catheterization procedures
involving real-time x-ray imaging.

3.

Conditions the exception to the lead apron requirement on the radiation
protection system being used according to the manufacturer's instructions.

4.

Limits the lead apron exception to health professionals working
primarily within a radiation protection system's designated safety zone.

5.

Clarifies that health professionals are not prohibited from voluntarily
choosing to wear a lead apron.

6.

Allows the Department of Health Services to adopt rules governing
radiation protection system requirements using an expedited rulemaking process.

7.

Defines
designated safety zone
.

8.

Makes conforming changes.

Amendments Adopted by the
House of Representatives

1.

Allows a hospital's radiation safety officer or designee to require
radiation protection equipment if staff exposure approaches occupational dose limits
under the
as low as reasonably achievable
standard.

2.

Removes the requirement for hospitals to instruct health professionals
to wear a lead apron in rooms equipped with a radiation protection system if
the health professional is not working primarily in the radiation protection
system's designated safety zone.

3.

Removes the authority for the Department of Health Services to adopt
rules governing radiation protection system requirements using an expedited
rulemaking process.

4.

Modifies the definition of
radiation protection system
.

5.

Makes technical and conforming changes.
