Initially, in her research at Dickinson College, Laws focused on the health applications and safety of
radiography and
X-rays, publishing several books on this topic: • ''Medical and Dental X-Rays: A Consumer's Guide to Avoiding Unnecessary Radiation Exposure'' (Public Citizen Health Research Group, 1974) •
X-rays: More Harm Than Good? How You Can Protect Yourself From Unnecessary Radiation By Understanding the Uses and Misuses of Diagnostic X-rays (Rodale Press, 1977) • ''The X-ray Information Book: A Consumers' Guide to Avoiding Unnecessary Medical and Dental X-rays'' (Farrar, Straus, Giroux, 1983) In the mid-1980s, Laws shifted her focus to
physics education. Her work in this area again includes several books in the
Workshop Physics and
RealTime Physics textbook suites, and the textbook
Understanding Physics (with Karen Cummings, Edward F. Redish, Patrick J. Cooney, and Edwin Taylor, John Wiley & Sons, 2012). ==Recognition==
