StemRad has made personal protection from radiation possible, making the lives of first responders, soldiers and astronauts safer while they complete their critical tasks. Through scientific breakthrough, StemRad has enabled shielding to save lives.

In the event of exposure to high doses of radiation, the leading cause of death is damage to the individual’s bone marrow, the body’s blood factory. In the event of protracted exposures to low doses, cancer may emerge in radiation sensitive organ.

“Underlying bone marrow failure from the external whole body irradiation was the major contributor to all Chernobyl deaths during the first two months”.

Our Solution - Selective protection against radiation


StemRad’s solution is to harness the regenerative capability of stem cells to allow the body to recover after exposure. We do so by selectively and effectively shielding the bone marrow and other stem cell rich organs in the abdominal and pelvic regions such as the ovaries, colon and bladder. This is the only way to provide meaningful protection while remaining mobile. Competing whole body solutions offer little to no protection from penetrating radiation such as gamma rays as they would have to weigh a quarter of a ton to do so.

“While whole body shielding is inherently heavy, partial body shielding is lighter in weight and selectively shields tissues of increased radiosensitivity (i.e. bone marrow) with substantial amounts of shielding material to protect hematopoietic functions; therefore, potentially preventing the acute health effects of exposure to gamma radiation (i.e. Acute Radiation Syndrome -ARS)”.
