title: [Evaluation ultraviolet radiation penetration into human skin. II. experimental studies].
abstract: Direct reflections of ultraviolet (UV) radiation (280-400 nm wavelength) from the human skin were characterised for different types of individuals. On the ground of this characteristics, the total UV reflection coefficient in this range was estimated. A new, noninvasive method for measuring a linear absorption and dispersion coefficient of UV radiation in skin layer was proposed. It is based on the measurement of radiant flux dispersed inside the skin cover during its radiation by a beam with a given profile. The dispersive flux is measured beyond the light zone. The absorption and dispersion coefficients can be calculated according to formulas developed previously and published in part I--"Theoretical analysis". Preliminary measurements of the above mentioned parameters were performed for different types of individuals.
