Over Head High Voltage (OH-HV) OH-HV radiate Extremely low frequency electromagnetic fields ( ELF-EMF) - OH-HV EMF pulse 60 times/sec INTRODUCTION

... Illustrations  Fluorescent light bulbs lighting up No batteries Not plugged in to power sources No connections to the ground

LONG TERM EFFECTS ( Under 345 kV, 500 kV) Sperm count Dynamic state of central nervous system Heart, vessel system Blood structure SHORT TERM EFFECTS Headaches Abnormal fatigues Sleepiness EVIDENCE AGAINST HIGH VOLTAGE POWER LINES

Emphasis on subject within m 1.Power line is a dominant source of magnetic fields. 2.Risk of poor mental health. 3.Biological effects 4.Childhood leukaemia.

Extremely low frequency EMF field Biological effect. Exposure to intense fields Exposure to Less intense fields Magnetic phosphenes : the stars and colours you see when you run your eyes

EMF and childhood leukaemia Ahlbom, A. Et al. (2000). A pooled analysis of magnetic fields and childhood leukemia British journal of cancer, Vol 83(5), p , 7p

Small sample size ( 10 linemen) Only 10 subjects lived within 100 m Low anticipation rate 23% 45% of women were worried – only a mental state REFUTATIONS

Emphasis on subject within m 1.Power line is not always a dominant source of magnetic fields. 1.No biological effects 1.Childhood leukaemia.

Biological effect? EMF and DNA EMF possess insufficient energy to disrupt DNA covalent bonds

Theoretical & observational confirmations for EMF to influence human health. Acute health effects in long term experiments Limited evidence. Possible biases Flawed studies No significant causal relationship CONCLUSION

Some high voltage lines are better than others 'The land of giants' ISLAND
