The Cripples -- Pieter Brueghel the Elder 
SPF (Sun Protection Factor) is a measure of how well a sunscreen protects skin from UVB rays. Ultraviolet radiation is part of the electromagnetic spectrum (light) from the sun. Its wavelengths are shorter than light visible to the human eye. It is the main cause of nonmelanoma skin cancers), including basal cell carcinoma and squamous cell carcinoma and perhaps also melanoma, the deadliest form of skin cancer. The shortest UV rays (UVC) are mostly absorbed by the ozone layer. The longest ones (UVA) account for about 95% of the ultraviolet radiation that reaches the Earth's surface. They are present with relatively equal intensity during all daylight hours throughout the year, and can penetrate clouds and glass. They play a major part in skin aging and wrinkling and damages skin cells called keratinocytes in the basal layer of the epidermis, where most skin cancers occur, so it contributes to and may even initiate the development of skin cancers. UVA is the dominant tanning ray, and, since tans are caused by injuring the skin's cellular DNA, leading to genetic mutations, and the skin darkens in an effort to prevent further DNA damage, thus causing cumulative damage over time. UVB is the range between A and C. Its intensity varies by season, location, and time of day but do not significantly penetrate glass. UVB is the chief cause of skin reddening, sunburn, and cancer. SPF does not measure how well a sunscreen protects from UVA rays, only UVB. For best protection, a minimum SPF sunscreen of 15 is recommended, about 1 oz. for full body coverage, reapplied every 2 hours. Since the SPF scale is not linear, SPF 30 only provides 4% more protection than SPF 15 (though it will block 1/2 the radiation that SPF 15 would let through).
ReplyDeleteDuane, thank you, I love the images you chose to illustrate my poem, especially the third. And the SPF introduction is the voice of a true expert!
