ABSTRACT: Objective: This study is designed to measure the current level of Indoor Electromagnetic Radiation (IER) in Chongqing, a municipality of western P.R. China, on which further epidemiological investigation on the relation between the level of IER and certain health effects could be based. Methods: 118 Households in 4 urban residential districts in Chongqing were randomly selected. The IER intensity was measured in each household’s living room at different frequencies under three different conditions. Results: The average electric field intensity measured at the frequency range of 1 MHz- 40 GHz was within the guidelines set by the International Commission on Non Ionizing Radiation Protection (ICNIRP). The electromagnetic field intensity measured at other frequencies were at the lowest range of the acceptable values. The average electric field intensity at the frequency range of 5 Hz - 1 kHz was higher at a standing posture than at a sitting posture with domestic appliances turned off in both cases (P
