About Us


The needs and requirements of modern nuclear operations demand sophisticated capabilities in the areas of radiological protection and health physics, compliance assessments, radiological engineering, occupational safety, industrial hygiene, nuclear shielding analysis, and other support services. M.H. Chew & Associates, Inc. is a professional consulting firm specializing in these and other scientific and technical services.

For over 31 years, M.H. Chew & Associates, Inc. has grown from a small, localized firm to a national organization that can support a large number of concurrent projects using highly qualified personnel with specialized capabilities and credentials. We have been providing radiation safety and other scientific consulting services to the U.S. Department of Energy (DOE), its National Laboratories and prime contractors and other government agencies including the National Institute for Occupational Safety and Health (NIOSH). Our staff includes two former presidents of the Health Physics Society, Certified Health Physicists (CHP), Certified Industrial Hygienists (CIH), other disciplined engineers including radiological engineers, nuclear engineers, chemists, physicists and mathematicians. Many of our staff maintain active DOE “Q” clearances.

​​​​​​​Along with the company’s established reputation in providing scientific consulting services, we have added a corporate emphasis in providing contracted labor of highly skilled technical professionals to support major programs and projects. We specialize in providing placement services in the nuclear (generating and non-generating), environmental, refining and utility industries on a temporary, temp-to-hire, or direct placement basis.
