From 1955 to 1958, Grodzins was a researcher with the nuclear physics group at Brookhaven National Laboratory, probing the properties of the nuclei of atoms.
In 1956, together with Maurice Goldhaber and Andrew Sunyar, Grodzins performed an experiment that determined that neutrinos have negative helicity.
This work was important in our understanding of the weak interaction.
Grodzins joined the faculty of the Physics department of MIT in 1959 and was a Professor of Physics there from 1966 to 1998.
In 1985, he carried out the first computer axial tomographic experiment using synchrotron radiation.

Meanwhile, in 1987, he co-founded and led research and development at Niton Corporation, which developed, manufactured and marketed test kits and instruments to measure radon gas in buildings and toxic elements, such as lead.
There he also developed handheld devices that use X-ray fluorescence to determine the composition of metal alloys and to detect other materials.
In 1998, he left MIT to work full-time directing the R&D group at Niton, and in 2005, he and his family sold Niton.
His sister Ethel was the President and CEO of Niton.
He also developed devices to detect explosives, drugs and other contraband in luggage and cargo containers.
Four of his devices have earned R&D 100 awards, given annually by R&D Magazine to the 100 most innovative technical products in the US.

Grodzins has written more than 150 technical papers and holds more than 50 US patents.
He was a Guggenheim Fellow in 1964–65 and in 1971–72, and a Senior Alexander von Humboldt Fellow in 1980–81.
He is a Fellow of the American Physical Society and the American Academy of Arts and Sciences.
He received an honorary Doctor of Science degree from Purdue University in 1998.
He is a founding member of the Union of Concerned Scientists and was its president in 1972.
In 1999, he founded Cornerstones of Science, a public library initiative to help children and adults explore science.
He serves as its president.
MIT has named the Lee Grodzins Postdoctoral Fellows Lecture Award for him.
