1 Non-thermal effects of Magneticfields on living things at OMP-Belin Nicolas Bouché (IRAP) CR1 (CNRS) 2012 UMASS PhD 2003 Commission H&S (IRAP)

2 Non-thermal effects of Magnetic-fields on living things Tesla ou Gauss?

3 Non-thermal effects of B-fields 1) Non-thermal effects on living things 2) OMP-Belin & safe limits 3) Precedents, Hopital Paul Brousse, Villejuif 4) Solutions & Discussion

4 Physics 101: Maxwell's Equations Gauss Law Induction Ampere's law

5 Magnetic Fields

6 Magneto-receptors in animals? Bees, termites, lobsters, pigeons, salmons, rodents, bats, cetaceans, worms, bacteria,... Sensitivity to AND/OR amplitude (50 μt)

7 Natural Background: Daily Variations +/- 20 nt Observatoire Geophysique de Paris 25 nt -25 nt Tesla

8 B-field in Tesla

9 Magneto-reception in living things

10 Magneto-reception in bacteria Static B-field Magnetobacterium Effect discovered in 1970s magnetites present in birds, trouts

11 Honey Bees Lost if hive moved by as little as 3meters Walker et al Tesla Perturbed Anomaly (1-50 Hz)

12 Magneto-reception in Monarch butterfly

13 Monarch butterfly Nature, 2014 But, need UV light: They are lost when antennas are painted or when 400nm light blocked!

14 Magneto-reception in Flies Magnetic-eyes? In 1998: discovery of a blue-light photoreceptor protein Cryptochrome that generates radical pairs when exposed to light confirms Schulten et al Found in Drosophilia, Monarch Butterflies Found in migratory birds Found in humans retina Foley et al. 2011, Nature See Review in The-Scientist.com

15 Quantum vision

16 Magneto-reception in Tesla Evidence on white blood cells Leukicytes, Neutrophiles Evidence on melatonin (since 1987) no/little effect <2 weeks for B of >1μT; Positive effect >4weeks for B of >1μT;

17 Magneto-receptors in cattle, deer? Tesla Burda et al disturbed by power-lines at >0.5μT

18 Effects in Humans?

19 Effects in Humans? Halgamuge et al Epidemiology studies no dose-response! Guenel et al.1996

20 Effect in Humans?

21 Melatonin & B-field in vitro Tesla Cid Human liver cancer cells - sensitive to Melatonine&Bfield

22 Alzheimer / Dementia Unconfirmed, but see SCENIHR report 2014

23 Man-made, Maximum Source: RTE kv Tesla

24 Epidemiology: Child Leukemia Tesla Confirmed in Pooled analysis in CA, US, UK, DE (ICNIRP reports): Elevated risks for child leukemia when B-field > 0.4 μt Positive results since Wertheimer & Leeper 1979 Risk 1.5x to 3x OMS carcinogen WHO / IARC classification as possible carcinogen - class 2B

25 Let's recap! Tesla? Child Leukemia Safe?

26 B-field in Tesla Safe? 800 Amps in ceilings

27 ICNIRP limits: Instantaneous from INDUCTIONTesla J in ma/m2: Faraday: 100 μt 0.2 to 2 ma/m2 <2 electrical cellular noise 2 10 neuroendocrine alterations above neuronal stimulation (brain) 1000 life threatening (cardiac extrasystoles) NO long term effects! (Directive EU ) Normes de 3 types: Pays-bas: <0.4 μt (for schools) Russia: <10 μt (legal level) Belgique, Italie: 10 et 6 μt (legal level)

28 EU new directive 2013/35

Official limits: Historical notes Alice Stewart (UK MD) found association between Leukemia and Xray (1950) Xray at safe dose! Official in 1975 (25yr later)!

29 Official limits: Historical notes Alice Stewart (UK MD) found association between Leukemia and Xray (1950) Xray at safe dose! Official in 1975 (25yr later)! Honory Prof. At age 90 (2002)! En Science comme ailleurs, l'intertie intellectuelle, la mode, le poids des institutions et l'autoritarisme sont toujours à craindre Hubert Reeves

30 Long-term human studies are un-ethical Lessons from Precedent in Paris Tesla White blood cells Hopital Paul Brousse ON ON Months Bonhomme-Faivre 1998

31 Lessons from Precedent in Paris Tesla Known in military circles Bonhomme-Faivre 1998

32 AC Magnetic Tesla Summary: >10 μt (high is >0.5 μt) Corresponds to living under power-lines. No major risk for adults (today)! Risk for Alzheimer cannot be excluded Associated with leukemia in children: Risk x2 if > 0.5 μt Official limit from instantaneous induced current: 100 μt 0.2 to 2 ma/m2 Don't take my word for it! Safe?

33 Make up your own mind! Biblioplanet pubmed etc.

34 Opportunities! Medical / Environment Bio Magnoreception (Astro)Physics Biology Biochemistry

35 Solutions 1) Do Nothing 2) Move to another lab? Meditate? 3) A new electric installation? New Building?

36 Solutions 3) A full survey of site (devis ready) 4) Balance the 3 phases

37 What s next to save money? What has already been done? Measures at 3 points (by EXEM; March 2014) H&S IRAP in the loop Direction OMP in the loop A working group OMP-wide? A teleconf with Laurence BF

38 Avoid making assumptions Are limits relevant? Implicit model!! What about Resonances? Which Freq(s)? What about the Earth B-field?
