Laser Radiation Detectors to levels as small as the Accessible Emission Limit (AEL). AELs range in value from tenths of microwatts or microjoules in the visible and near infrared (400–1400 nm) to millijoules in other parts of the spectrum. Hazard classification at the Class 4 level requires that cw radiant powers of at leas

Quantitative Determination of Ultraviolet Radiationg instruments may be used when high accuracy is really not necessary. Polysulphone film detectors may be used in those situations where direct reading is not feasible, several simultaneous measurements are desired, or in a harsh environment where electromagnetic interference is present. The exposed

Anatomy and Physiology of the Skinon by means of the fingerprint patterns. The lost of elasticity, and an increase of folds and ridges are characteristic of the skin aging, together with the appearance of brownish stains. The colour of the skin is largely variable according to the race, sex, age, vasodilatation, effort, emotional st

Potential Ocular and Skin Hazards from Lamps and Projector SystemsLimit Values Suggested Changes for 1990 (ACGIH, 1990) suggest that sources such as tungsten halogen lamps can exceed exposure limits for short wavelength visible light. This is commonly referred to as the “blue-light” hazard. Allistair McKinlay describes this standard in detail in another section of
