by Karl Riley
Could have been called: "What to Do with Your New Gaussmeter". A general introduction to the measurement of magnetic fields in home and work environments. Explains in detail how to use a gaussmeter; gives hints about measuring fields in homes, schools, and offices; and offers useful background information on risks, mitigation, and magnetic fields. A great manual to accompany any gaussmeter purchase. 1993

THE POWERWATCH HANDBOOK
Simple Ways To Make You And Your Family Safer
by Alasdair and Jean Philips
Are you keeping safe? Electrical wiring and appliances, overhead power lines, machinery, photocopiers, mobiles and cordless telephones, radio masts, TVs, tube trains, x-rays and laser beams are amongst the hundreds of everyday items that are now known to give off high levels of EMF. Electromagnetic fields (EMFs) can be biologically active and capable of making changes to the structure of human and animal cells which are exposed to them. Long-term exposure is believed by an increasing number of scientists and environmentalists to be connected to tumors, fertility problems, behavior and mood changes, concentration and memory loss, and also to affect melatonin production and impair our immune system repair mechanisms. The Powerwatch Handbook is a simple no-nonsense guide to EMFs and how to reduce their harmful effect. Here is practical information on:
- How to test for EMFs in the home
- Star ratings for different items and products
- Simple ways to reduce your exposure to high level pollution
- Reduce the effect of telephones, mobiles, TV masts and other outside sources
- EMFs at work and in hospitals, dental surgeries and shops
- How EMFs affect babies and young children
- How to avoid becoming electrically sensitive
Information is presented in a practical, positive and lively way, in an easy-to-follow handbook style. EMF levels are graded using a star rating system, high level items are highlighted, and practical tips given in step-by-step, bullet point form. 256 pages, 2006

TRACING EMFs in Building Wiring and Grounding
2nd edition, by Karl Riley
A practical guide for reducing AC magnetic fields produced by building wiring and improper grounding practices. Step by step instructions for detecting wiring problems and a full description of common wiring errors and how to correct them. This guide is for anyone who wants to inspect their own home, electricians and electrical inspectors, those starting a new profession in EMF consulting, as well as those involved with the process of building construction such as architects and contractors. Utility personnel involved in EMF measurements can profit from this information. 96 pages, spiral bound book. Completely updated in 2005.

TRACING MAGNETIC FIELDS IN BUILDING WIRING DVD
by Karl Riley
This DVD graphically explains how certain wiring errors create high magnetic fields. It shows step-by-step methods of measuring the fields and then how to find the faulty circuit and the wiring error. Created under a grant from California Health Services to help school electricians reduce the magnetic fields found in the state's schools during a 90-school magnetic field survey. Filmed by the video dept. of Southern California Edison and using their graphics animation to show how the currents move in misconnected circuits. Written and hosted by Karl Riley, author of Tracing EMFs in Building Wiring and Grounding. 23 minutes.

A Design & Specification Guide by Leland Hemming
by Hubert Trzaska
Laboratory studies of electromagnetic (EM) signal propagation through construction materials were carried out as part of the NIST initiative. In this report, power attenuation aspects are discussed. The materials investigated included brick, masonry block, eight different concrete mixes, glass, plywood, lumber (spruce-pine-fir), drywall, reinforced concrete, steel reinforcing bar grids, variations of the plywood and lumber tests in which the specimens were soaked with water, and composite specimens involving brick-faced masonry block and brick-faced concrete. For each material, varying thickness specimens were fabricated in order to measure attenuation as a function of penetration distance. Measurements of power loss were taken at 2 MHz intervals from 0.5 to 2 GHz and from 3 to 8 GHz. Frequency power spectra were discretely generated for each material as a function of thickness. Excellent tables and graphical data. Extremely useful for predicting the shielding effectiveness of common building materials. 200 pages, 1997.
