Observations and context

Barbara Askins' method promoted improvements in the development of X-ray images. Thus, medical images that were underexposed by 96% became legible. This resulted in doctors being able to dramatically lower the level of X-ray exposure to their patients.
 
We can relate her to other contemporary scientists, such as Irene Joliot-Curie, physicist, chemist, politician, anti-fascist activist and French feminist; Dorothy Cowford, who discovered the structure of penicillin and that allowed it to be used as an antibiotic; Gertrude Elion, American biochemist and pharmacologist, who received the 1988 Nobel Prize in Physiology and Medicine for her "discoveries of key principles of drug development and treatment"; Rosalind Franklin, British chemist and crystallographer whose work was instrumental in understanding the molecular structures of DNA (deoxyribonucleic acid), RNA (ribonucleic acid), viruses, carbon, and graphite; Dorotea Barnés, one of the Spanish pioneers in chemistry, both in research and teaching, during the Silver Age.
