Health Physics Society Journal

Health Physics Journal,
Vol. 76, No. 4, April 1999 On the cover: Cross section of an eye showing the propagation of a laser beam focusing on the retina. The retina is especially susceptible to damage from laser radiation in the retinal hazard regime (0.4-1.4 mm). Maximum exposure limits exist for most exposure durations except those shorter than one nanosecond. In an article by Roach et al., maximum exposure limits in this ultrashort laser pulse regime are proposed. (Graphic provided by B. Rockwell.)
