The use of electrical appliances has enhanced the quality of life. As a result, the electricity demand rapidly increased. Although it provides advantages to life, people are exposed to the electromagnetic field radiation without realizing it. This study focuses on the impact of electromagnetic field radiation on the human muscles by using Electromyography (EMG) apparatus. The radiation is measured from the electrical appliances inside the office room with fluorescent lights as well as a computer with liquid crystal display (LCD) and cathode ray tube (CRT) screen. 17 subjects with no history of chronic musculoskeletal or abdominal pain participated in this study. The EMGs of the forearm muscles, including flexor carpi radialis (FCR), extensor carpi radialis longus (ECRL), flexor carpi ulnaris (FCU), and extensor carpi ulnaris (ECU) are recorded with a sampling rate of 2,000 Hz. The analysis of variance (ANOVA) is performed to determine the impact of electromagnetic field radiation on the forearm muscles. It is found that CRT radiation has a significant effect on the forearm muscles.
