We have developed the exclusive GERM-AWAY UVC product line to provide something for everyone and matching the best product to the best application purpose. ARPANSA monitors and reports UV dose throughout the day in major Australian cities in units of Standard Erthermal Dose (SEDs). The higher frequencies of EM radiation, consisting of x-rays and gamma rays, are types of ionizing radiation. Dosage is a combination of exposure time and intensity (microwatts per square centimeter). The highest UV intensity is reached when the sun is at its highest point in the day, halfway between sunrise and sunset — called solar noon. The minimal erythemal dose is used to calculate the duration of therapeutic exposure to ultraviolet light. UV Dose Terminology. UV-AST 250 beads - 25 bracelets - 25' = nine yards of UV-RAW.
