ELECTROMAGNETIC SIGNAL ATTENUATION IN CONSTRUCTION MATERIALS

NIST Construction Automation Program Report No. 3

NIST REport #3 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.

HANDBOOK OF MAGNETIC MEASUREMENTS

Living Without Elecricity

By Slawomir Tumanski

While magnetic devices are used in a range of applications, the availability of up-to-date books on magnetic measurements is quite limited. Collecting state-of-the-art knowledge from information scattered throughout the literature, Handbook of Magnetic Measurements covers a wide spectrum of topics pertaining to magnetic measurements. It describes magnetic materials and sensors, the testing of magnetic materials, and applications of magnetic measurements.

Suitable for specialists as well as readers with minimal knowledge of magnetic measurements, the book begins with an easy-to-follow introduction to the essentials of magnetic measurements. It then offers a comprehensive review of various modern magnetic materials, such as soft and hard magnetic materials and thin magnetic films. The text also describes all commonly used magnetic field sensors, including inductive, fluxgate, Hall, magnetoresistive, resonance, SQUID, magnetoelastic, and magneto-optical sensors. The final chapters discuss the nondestructive testing of materials and explore applications related to magnetic measurements, including magnetic diagnostics in medicine, magnetoarcheology, and magnetic imaging. 404 pages, 2011

LIVING SAFELY WITH ELECTROMAGNETIC RADIATION

by Jim Waugh

Different than most books on the subject because it discusses the theory and background behind EMR in Part 1 and then explains what the reader can do to reduce his or her exposure in Part 2. It is a well researched book that explains complex terms and issues clearly in a very readable form.

It gives simple, do-able steps for testing your living environment to reduce the risks of developing EMR sensitivities and diseases. Numerous recommendations assist the reader in using electrical and wireless technologies safely.

    Topics addressed in Part 1 Living Without Elecricity
  • What EMR is, where it comes from and the reasons for concern
  • How EMR impacts the human body
  • Explanations of EMR terminology
  • Impact on the natural environment
  • Wireless networks and power transmission lines
  • Cellphones
  • Geomagnetic energy
  • Roles of government and industry
    Topics addressed in Part 2
  • Safe exposure standards
  • Building or renovating an electromagnetic safe home
  • Toxic chemicals and EMR
  • Electromagnetic home investigation
  • Real estate pre-commitment investigation
  • EMR in passenger vehicles

Appendices and a bibliography list sources of people, materials, tools and reference material. Paperback. 2010, 234 pages.

THE POWERWATCH HANDBOOK

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
