Nonionizing Radiation: Radiofrequency

Photodynamic Therapy: Occupational Hazards and Preventative Recommendations for Clinical Administration by Healthcare Providers

“…Certain factors of clothing that may affect radiation protection include the material, weave, color, stretch, weight, quality, and water content. 48 Generally, radiation may leak through the mesh of woven fabrics, and often cotton or polyester-cotton blends do not offer consistent radiation protection. One measure of the ability of a fabric to protect against radiation is the UV protection factor (UPF), defined as the ratio of effective UV dose for the unprotected skin to the effective dose to protected skin.…”

“…Therefore, an OD of 1 will have an attenuation of 10, whereas an OD of 6 will have an attenuation of 10 6 . 48 The recommended levels of attenuation required for a given light source can usually be found in the manufacturer's product literature. Because healthcare providers have to view the patient and the treatment area, the optical filters must both protect against light source radiation and allow sufficient transmission of daylight to enable viewing.…”
