With widespread users across the globe, topic on the impact of mobile phone in particular regarding its electromagnetic wave radiation deserves a priority. Carcinogenic effects of the electromagnetic wave radiation have been suggested by multiple studies. Effects of the radiation are to involve thermal and non-thermal pathways. Among human organs, thyroid gland is susceptible to the radiation exposure due to its location being superficial and close to the radiation transmitter. Previous studies have indicated the correlation between the mobile phone radiation and thyroid dysfunctions. However, a conclusion that the electromagnetic wave radiation is the causative agent of the thyroid dysfunctions has not been reached. Most of the study are unable to remove the influence of the external electromagnetic wave radiation. Hence, this study aimed to perform an investigation with true experimental design using animal model in an anechoic chamber - an isolated chamber which could minimize the electromagnetic wave noise from the outside. In this article, we present the description of the anechoic chamber along with the research protocols. Parameters affecting the investigation, including signal frequencies inside the chamber and specific absorption rate are also measured.
