RT Journal A1 Greist MC T1 ULtraviolet radiation in medicine JF Archives of Dermatology JO Archives of Dermatology YR 1984 FD September 1 VO 120 IS 9 SP 1246 OP 1246 DO 10.1001/archderm.1984.01650450128042 UL http://dx.doi.org/10.1001/archderm.1984.01650450128042 AB Ultraviolet Radiation in Medicine is a concise discussion of the history, physics, biological effects, and medical applications of UV light.The initial chapter on the history of UV radiation is well written. The major difficulty I have with the book first appears in the second chapter on the production of UV irradiation. An overabundance of highly sophisticated mathematics is interlaced with some poorly defined concepts to create confusion for the reader. A paragraph beginning on page 20 exemplifies both problems.The function F(λ, h, x). This function has been empirically derived from the data presented by Bener (1972) and is not meant to represent mathematically any physical phenomenon.It has been found that the function may adequately be represented byF(λ, h, x) = exp[—μ(χ — 0.32)Q],where μ = exp[0.135(320 — X) — 0.4345]. The parameter Q is given by either Q = 1.0 for λ ≥ 330 nm....The discussion of
