The mission of the Indoor and Radiological Health (IRH) Branch, formerly
known as the Noise, Radiation and Indoor Air Quality (NRIAQ) Branch, is to conduct assessment,
develop policy, and provide assurance in the fields of community noise control, radiation
control, mechanical ventilation, indoor air quality, asbestos abatement, and lead-based paint
The IRH Branch strives to promote public health in the community,
minimize morbidity and mortality from specific public health hazards, and optimize regulated
activities and workplaces. The resources of the IRH Branch are directed at those problems
that pose the greatest risk to optimal public health.
The IRH Branch has its roots in the Department of Health’s former
Bureau of Industrial Hygiene in the territorial days. In subsequent years, records revealed
an Occupational Health-Radiological Health Branch. In the early seventies, the Occupational
Health component of the branch was transferred to the State Department of Labor and Industrial
Relations where it became the core for today’s Hawaii Occupational Safety and Health Division
(HIOSH). In the same period, a noise program was developed in the branch via grant monies from
the U.S. Environmental Protection Agency (EPA). Henceforth, the branch became known as the
Noise and Radiation Branch. In the 1990’s, EPA-funded activities for indoor air quality,
asbestos certification and accreditation, asbestos abatement notification, asbestos in schools,
and lead-based paint were added to the branch. Today, we have a total of six programs in the
Indoor and Radiological Health Branch: noise, radiation, air-conditioning/ventilation, indoor
air quality, asbestos and lead.

An Administration Unit responsible for planning and implementing program policies,
procedures, and services according to standards.
Our branch is one of four branches in the Environmental Health Services
Division (EHSD). The other branches are Sanitation, Food and Drug, and Vector Control.
Essentially, EHSD is an organization of traditional public health sections. EHSD’s sister
division is the Environmental Management Division (EMD), consisting of environmental protection
sections such as Clean Air, Clean Water, Solid and Hazardous Waste, Safe Drinking Water,
and Wastewater. Both EHSD and EMD constitute the Environmental Health Administration (EHA) in
the Department of Health.
The IRH Branch consists of:
The Noise Program implements the the community noise program. This includes enforcement
of maximum permissible sound levels for stationary noise sources and issuance of permits for
agricultural, construction, and industrial activities.
The Radiation Program provides radiological incident response to control release of
radioactive materials, licensing of all radiation facilities with electronic products emitting
ionizing radiation and/or non-fission radioactive materials, licensing of radiation services
such as x-ray equipment installation and medical physics, and providing administrative support
to the Radiologic Technology Board’s licensing of radiographers, nuclear medicine technologists,
and radiation therapists.
Air Conditioning/Ventilation Program - administers the provisions pertaining to air
conditioning and ventilation systems.
The Asbestos and Lead Program consists of three programs:
Indoor Air Quality Program - administers the provisions relating to indoor air quality.
Asbestos Abatement Program - administers the provisions relating to asbestos.
Lead-Based Paint Program - administers the provisions relating to lead in paint.
