Radiation Hazzards Within a Company

(Ng , 2003 . The table below summarizes the biological effects of the different types of non-ionizing radiation (Ng , 2003

Wavelength , frequency Biological Effect

UVC 100nm - 280nm Skin - Erythema , inc pigmentation

Eye - Photokeratitis (inflammation of cornea

UVB 280nm - 315nm Skin - Erythema , inc pigmentation , photosensitive skin reaction , skin cancer

Eye - Photokeratitis (inflammation of cornea

UVA 315nm - 400nm Skin - Erythema , inc pigmentation , skin photo-ageing skin cancer

Eye - Photochemical cataract

Visible 400nm - 780nm Eye - Photochemical and thermal retinal injury

IRA 780nm - 1 .4 ?m Skin - Skin burn

Eye - Thermal retinal injury

, thermal cataract

IRB 1 .4 ?m - 3 ?m Skin - Skin burn

Eye - Corneal burn , cataract

IRC 3 ?m - 1mm Skin - Heating of body surface

Eye - Corneal burn , cataract

Microwave 1 GHz - 300 GHz Heating of body surface

100 Khz - 1 GHz Heating with penetration depth of 10mm , raised body temperature 0 Hz - 100 KHz Cumulation of charge on body surface , disturbance of nerve and muscle responses

Static 0 Hz Magnetic feild - vertigo and nausea

Electric field - charge on body surface
