StemRad is developing Personal Protective Equipment (PPE) to protect against the deadly effects of radiation sickness, also known as Acute Radiation Syndrome (ARS), and is endorsed by a renowned scientific advisory board, which includes two Nobel Laureates and the world’s leading physicians in the treatment of radiation sickness.

StemRad is in the final stages of developing its protective device, which is in critical need by nuclear energy operators and safety forces. The recent disaster in Fukushima, Japan and the increasing threat of nuclear weapons proliferation, have highlighted the limited protective equipment which exists today to protect engineers and first-responders in cases of disaster.

By analyzing the specific locations within the human body which are damaged most, and which impact the survivability of the human body in the presence of high doses of radiation, StemRad has developed a device to protect professionals operating in such environments.



Dr. Milstein co-founded StemRad in November 2011, and has more than 10 years of Life Sciences research experience.  Formerly, Dr. Milstein was an EMBO fellow at NYU’s Skirball Institute of Biomolecular Medicine, where his research provided basic insights into the mechanism of T cell activation.   Later in his career, as an NIH fellow at the Scripps Research Institute, he discovered a novel mechanism for iron deficiency anemia. Subsequently, Oren focused his research on radiation-induced autoimmune hemolytic anemia. Dr. Milstein received his Ph.D. degree from The Weizmann Institute of Science in 2008, where he developed novel strategies for successful bone marrow transplantation into irradiated subjects. He received his B.Sc., Magna Cum Laude, from The Hebrew University in Jerusalem.  Until recently, Oren served also as Adjunct Professor of Immunology at Mount St. Mary’s College in Los Angeles. His research has resulted in several peer-reviewed publications and patents.
