Revision notes:
v2.5 (12-May-94) Numerous typos corrected, list of archive sites expanded,
expanded to 6 parts with "logical" break points.  Theriault [D10]
occupational and Rannug [G26] promotion studies added.  Section on
publication bias (Q21D) expanded.  The "hot dog" factor is discussed in
Q21B.  Data on residential and occupational electric fields added to Q10. 
The 6-part split was not approved, at date of posting, by the *.answers
moderators


Table of Contents:

Part2
1) Why is there a concern about powerlines and cancer?
2) What is the difference between the electromagnetic (EM) energy
associated with power lines and other forms of EM energy such as microwaves
or x-rays?
3) Why do different types of EM sources produce different biological
effects?
4) What is difference between EM radiation and EM fields?
5) Do power lines produce EM radiation?
6) How do ionizing EM sources cause biological effects?
7) How do RF, MW, visible light, and IR light sources cause biological
effects?
8) How do the power-frequency EM fields cause biological effects?
9) Do non-ionizing EM sources cause non-thermal as well as thermal effects?
10) What sort of power-frequency fields are common in residences and
workplaces?
11) Can power-frequency fields in homes and workplaces be reduced?
12) What is known about the relationship between powerline corridors and
cancer rates?
13) How big is the "cancer risk" associated with living next to a
powerline?
14) How close do you have to be to a power line to be considered exposed to
power-frequency magnetic fields?
15) What is known about the relationship between "electrical occupations"
and cancer rates?

Part3
16) What do laboratory studies tell us about power-frequency fields and
cancer?
    16A) Are power-frequency fields genotoxic? 
    16B) Are power-frequency magnetic fields cancer promoters? 
    16C) Do power-frequency magnetic fields enhance the effects of other
    genotoxic agents?
17) How do laboratory studies of the effects of power-frequency fields on
cell growth, immune function, and melatonin relate to the question of
cancer risk?
18) Do power-frequency fields show any effects at all in laboratory
studies?
19) What about the new "Swedish" study showing a link between power lines
and cancer?
20) What criteria do scientists use to evaluate all the confusing and
contradictory laboratory and epidemiological studies of power-frequency
magnetic fields and cancer?
    20A) Criterion One: How strong is the association between exposure
    to power-frequency fields and the risk of cancer?
    20B) Criterion Two: How consistent are the studies of associations
    between exposure to power-frequency fields and the risk of cancer?
    20C) Criterion Three: Is there a dose-response relationship between
    exposure to power-frequency fields and the risk of cancer?
    20D) Criterion Four: Is there laboratory evidence for an association
    between exposure to power-frequency fields and the risk of cancer?
    20E) Criterion Five: Are there plausible biological mechanisms that
    suggest an association between exposure to power-frequency fields
    and the risk of cancer?
21) If exposure to power-frequency magnetic fields does not explain the
residential and occupations studies which show increased cancer incidence,
what other factors could?
    21A) Could problems with dose assessment affect the validity of the
    epidemiological studies of power lines and cancer?
    21B) Are there other cancer risk factors that could be causing a
    false association between exposure to power-frequency fields and
    cancer?
    21C) Could the epidemiological studies of power lines and cancer be
    biased by the methods used to select control groups?
    21D) Could analysis of the epidemiological studies of power lines
    and cancer be skewed by publication bias?
22) What is the strongest evidence for a connection between power-frequency
fields and cancer?
23) What is the strongest evidence against a connection between
power-frequency fields and cancer?
24) What studies are needed to resolve the cancer-EMF issue?

Part4
25) Is there any evidence that power-frequency fields cause any human
health hazards?
26) What are some good overview articles?
27) Are there exposure guidelines for power-frequency fields?
28) What effect do powerlines have on property values?
29) What equipment do you need to measure power-frequency magnetic fields?
30) How are power-frequency magnetic fields measured?
