Personal UV Biodosimeter

UV radiation is paradoxically the source of concern and of benefit for the human body. Although type B ultra-violet radiation (280 – 315 nm) is increasingly monitored and screened as the cause of erythema-sunburn, premature aging of skin and even skin cancer, natural exposure to sunlight is undeniably responsible for the synthesis of 90% of our vitamin D. Exposure to sunlight is indispensable to the human body as it controls almost 2,000 of 10,000 human genes. Its effect on mineralization is recognized in many processes now beyond bone health. Vitamin D deficiency has been related to a number of chronic conditions and diseases in adults who are not exposed to adequate sunlight.* So what is the right amount of sunlight exposure? The VITA-D Biodosimeter bioequivalence technology is intended to enable a user to abandon arbitrary rules of thumb and determine more precisely the appropriate sunlight that allows harvesting the sun's benefits while avoiding its threats. * Vitamin D deficiency is linked to rickets, osteoporosis, and many chronic diseases such as cancer (breast, ovarian, colon and prostate), chronic pain, chronic fatigue, autoimmune diseases (multiple sclerosis, rheumatoid arthritis and Type 1 diabetes), high blood pressure, mental illnesses, heart disease, psoriasis and tuberculosis.
Patent Abstract: 
The VITA-D personal biodosimeter technology is designed to measure the vitamin D synthetic capacity of sunlight and/or artificial ultraviolet radiation in-situ, using the same photochemical process from which vitamin D3 is synthesized in human skin. The innovators envision two embodiments of this technology: Polymer films are doped with molecules of pro-vitamin D and are used as bio-analogue photo-registering elements.
