Abstract

Three cases of occupational exposure to radio-frequency and microwave radiation were seen at the out-patient clinic, Hospital Universiti Sains Malaysia. They presented with run-down symptoms of neck strain associated with throbbing headache, irritability, loss of appetite, fatigue, memory difficulties, and numbness of extremities. They also presented with alopecia areata which is felt to be causally linked to the radiation exposure.

Main findings

Three occupationally exposed cases to radio-frequency and microwave radiation presented with multiple non-specific symptoms and alopecia areata. The authors state the alopecia areata was felt to be causally linked to the radiation exposure.
