Abstract
Summary
Intense radiation up to 73 kr was applied locally to the forelimb muscles in a rat with its body otherwise shielded. Observations were confined to limbs not subjected to active fatigue following X-ray exposure. For up to 22 hr after exposure the muscles remain functional. However, the radiation produces marked extracellular edema as measured by inulin space and Na24 space determinations. The muscle fibers lose no K per unit dry weight but may possibly gain minimal Na as Na24.
