This book reports on the investigation of the public s perception of Radio Frequency Electromagnetic Field (RF-EMF) radiation effects on health and well-being, in Malaysia. It elaborates on how understanding the impact of perceived risk is essential in order to investigate the explanatory value and effectiveness of interventions influencing these beliefs. The book expands on the knowledge and understanding of different risk perception related to radiation in order to explain the gap in literature regarding the relationship between risk perceptions that lead to public behaviors. In doing so, the book presents empirical findings of a national study that unveils two key factors affecting public risk perceptions: psycho-graphic and personal factors. It offers a more collective and cultural understanding of public perceptions on radiation risks via a systematic mixed-method research approach.
