The efficacy of different methods for informing the public about the range dependency of magnetic fields from high voltage power lines risk

Risk perception

• risk estimation
• risk knowledge
• informing

Endpoint

• exploration of a number of strategies which might be used in risk communications to correct misperceptions

Considered exposure sources

• • 50/60 Hz
  • magnetic field
• • power transmission line
• • residential

Investigated group

112 members of 2 universities in the USA with no physics beyond high school level participated in the survey.

Replicated studies

• Morgan MG et al. (1990): Lay understanding of low-frequency electric and magnetic fields
