AstroRad Latest News

An Israeli company named StemRad has, along with Lockheed Martin, recently developed a vest called AstroRad for spaceflight.

About AstroRad

• It is a wearable, radiation-shielding vest designed for space travel by the Israeli company named StemRad, with support from the Israel Space Agency and Lockheed Martin. 
• It protects astronauts’ vital organs from dangerous space radiation beyond low-Earth orbit (LEO). 
• It reduces Radiation Exposure Induced Death (REID) while eliminating the possibility of Acute Radiation Syndrome (ARS) due to solar particle events.

AstroRad Features

• The AstroRad uses a proprietary smart shielding design to selectively protect those organs and tissues which are most sensitive to radiation in terms of REID probability. 
• This approach provides the greatest biological impact of protection with the least amount of mass. 
• Tissue-weighting factors are assigned to organs and tissues in the body to reflect the variance in radiation sensitivity, with organs such as the lungs, bone marrow, colon, stomach, breasts, and ovaries being among the most sensitive. 
• Selective protection of these organs, and tissue-resident stem cell concentrations within them was accomplished by designing variable shielding thickness to complement the body’s own shielding. 
• The shielding in the AstroRad comprises a polymer with a high abundance of hydrogen, which is advantageous for shielding against space radiation because it minimizes the generation of secondary radiation. 
• Individual solid shielding elements are organized into a scale-like architecture to allow for uninhibited, comfortable movement of the astronauts while wearing the AstroRad.
