A lead-free radiation protection material for use in radiation protection gloves to protect the wearer from scattered secondary radiation comprises at least one layer of a polymeric latex having lead-free radiation absorbing particles and a water soluble polymeric thickener distributed therein. In some cases, the system receives two or more data items to be stored on a storage medium, pre-allocates a single, contiguous block of space on the medium, and stores the two or more data items within the single, contiguous block of space. The second clutch device can be connected to the second section of the shaft to rotate the shaft. A condensing lens receives the substantially collimated light output and focuses the collimated light output to optically couple to an optical fiber. Single session hyperthermia and radiation therapy overcomes the thermotolerance-associated inefficiency of hyperthermia treatment as it is when hyperthermia is combined with fractionated, lower dose rate radiation. Manipulation between the digits provides precise finger-tip control of the pitch, angle and pressure applied the fixed or replaceable shaving blades.
