Radon is a naturally occurring radioactive gas that is emitted from soils and rocks and is in some water sources. The EPA promotes radon monitoring and sealing of homes to prevent an indoor radon gas hazard. The range of radon gas in US homes varies by a factor of over 1000.ddly, while some studies report a link between radon and lung cancer, there was no association for lung cancer among houses located near uranium or radium processing waste sites. At best, the association between radon gas and lung cancer is considered weak. [13]. How radon gas gets in your home.

Organization of Skeletal Muscle. Our bodies contain numerous skeletal muscle organs-for example, the biceps brachii of the arm and the gastrocnemius of the leg. The muscles that move and support our body are attached to bones at each end by what we call tendons.he muscle fiber membrane is called the sarcolemma. Skeletal muscle cells or fibers are composed of hundreds to thousands of contractile organs that we call myofibrils. Each myofibril runs the length of the muscle fiber. Remember, muscle fibers run the length of the muscle organ.
