She determined that developing embryos were most vulnerable to the effects of radiation during the first seven weeks of pregnancy and therefore recommended that non-urgent diagnostic X-rays be taken in the 14 days after the onset of a woman's menstrual period, a standard that became internationally accepted in radiological practice.

[6] Russell began her career as a research assistant at Jackson Memorial Laboratory from 1943 to 1947, and worked as a fellow at the University of Chicago.

[8] She and her husband established the "mouse house," a colony of more than 200,000 mutant mice bred to study the effects of radiation exposure.

Under her guidance, this Section expanded its research, studying the genetic effects of chemicals from drugs, fuels and waste on mice.

In 2013, Oak Ridge National Laboratory created the Liane B. Russell Distinguished Early Career Fellowship to assist young researchers.

After several years in England, Liane moved to the United States, where she decided to further her education at Hunter College in New York City.

[13] Interestingly enough, through the assistantship, her supervisor, William Russel, a leading geneticist at the time, would later become both Liane's husband and research partner.

Upon graduation from Hunter College in 1945, Liane went back to Jackson Laboratory before moving to the University of Chicago to pursue her Ph.D. in Zoology.

After initiating her Ph.D., Liane went to work at the Oak Ridge National Laboratory in Tennessee, which played a vital role in the development of nuclear weapons through the Manhattan Project in WWII.

Liane was fortunate enough to work alongside her husband, William Russell, as they both had a mission to study the effects of radiation exposure on mice.

The essential pain point Liane was looking to solve was that the current information surrounding the effects of radiation on congenital disabilities was insufficient and inconclusive.

However, despite heavy criticism, the innovative research that both Liane and her husband performed became known as the 14-day rule and became a radiological practice accepted in almost every country.

These findings have protected millions of pregnant women from premature radiation procedures that would have had detrimental effects on their pregnancies and children in the 1950s and the present day.

Inevitably, Liane Russell played a pivotal role in the radiation field and discovered its harmful effects on developing embryos.
