The amount of UVA radiation hitting a surface at sea level in a lightly clouded day isabout 70W/m2. About half of that can be absorbed by the skin. A typical carbon-carbon bond requires 348 kJ/mol to break. A person lies on the beach for about 1hour without sunscreen (i.e. fully exposed to UVA radiation). Estimate the numberof C-C bonds broken in this person’s back (about 0.18 m2) over that period. Assumethat the average wavelength of UVA is 335 nm.
