THE EPIDEMIOLOGICAL STUDY OF MONGOLISM IN BALTIMORE

Bernice H. Cohen, Abraham M. Lilienfeld · 1970

Mothers of children with mongolism reported significantly less often having no radiation exposure (50% vs 59.9%) than control mothers. The estimated relative risk for maternal radiation exposure was 1.5, corresponding to an attributable risk of 17%. Fathers of mongol children more often reported radar exposure (8.75%) than control fathers (3.3%), a difference of borderline significance.

Anthony Robbins, M.D. · 1970

The document reviews scientific information on radiofrequency and microwave radiation and recommends a standard for controlling workplace hazards. The recommended limits apply to frequencies from 300 kHz to 300 GHz and are averaged over any 6-minute period during a workshift of up to 10 hours.

Quantifying Hazardous Electromagnetic Fields: Practical Considerations

Ronald R. Bowman · 1970

Power density is only useful for simple, uniform plane-wave fields and is unsuitable for complicated fields with reactive components or multipath interference. The total energy density of the field is the best parameter for quantifying hazardous fields, though electric energy density alone is often adequate. The field parameter approach is considered the most practical for general survey measurements.

ON THE POSSIBILITY OF NONTHERMAL BIOLOGICAL EFFECTS OF PULSED ELECTROMAGNETIC RADIATION

LAWRENCE D. SHER, EDWARD KRESCH, HERMAN P. SCHWAN · 1970

The study examined two mechanisms for alternating electrical fields interacting with biological tissue: heat development and field-induced force effects. For continuous wave fields in physiologic media, heating above 1°C always occurs before any field-induced force effect can appear. Using pearl-chain formation as a model, the researchers demonstrated that pulsed fields offer no greater likelihood than CW fields of equal RMS strength for producing pearl-chain formation.

APPLICATION OF MICROWAVE FREQUENCY MEASUREMENTS TO IDENTIFY PATHOLOGICAL COMPOUNDS IN BIOLOGICAL SPECIMENS

K. Bakin, E. E. Stickley · 1970

Dielectric relaxation times of dipole liquids are directly proportional to molecular radius and viscosity and inversely proportional to temperature. The Debye model, modified by a form factor for non-spherical molecules, can characterize molecular size and form from dielectric properties. Exploratory trials tested whether the method could detect shape or configuration variations in compounds from pathological situations. The method's sensitivity appeared to support its applicability, with further refinements in development.

Biological Effects and Health Implications of Microwave Radiation

Stephen F. Cleary · 1969

The symposium was convened to provide an indication of the present state of the art in biological effects of microwave radiation. There is a great deal of uncertainty concerning the effects of low-intensity microwave and radio-frequency radiation on the mammalian central nervous system. The lack of measurement standards makes intercomparison of data from different investigators difficult or impossible. Federal responsibility for radiation control was established under the Radiation Control for Health and Safety Act of 1968.

Microwave Protection of Plants from Cold

R. G. Bosisio, N. Barthakur · 1969

Researchers measured a reflection coefficient of one per cent and a transmission coefficient of 85% for wax bean leaves at 915 MHz. In a cold chamber at —5°C, microwave radiation of intensity 15 mW/cm² at 2450 MHz raised the leaf temperature to 25°C. The protected plant maintained a leaf temperature of 25°C while the unprotected plant cooled to the ambient temperature of —5°C. After 4 hours the protected plant was still fresh and growing normally, whereas the unprotected plant was completely destroyed.

THE EFFECTS OF LOW LEVEL MICROWAVE IRRADIATION UPON REFLEXIVE, OPERANT, AND DISCRIMINATION BEHAVIORS OF THE RAT

Nancy Williams King · 1969

Low-level irradiation (1.5–1.7 mw/gm) reduced responding when correlated with reinforcement or extinction but had no reliable effect during uncorrelated presentations. Low-level microwave irradiation did not act as a discriminative stimulus, although acoustic and visual stimuli were well discriminated. High-level irradiation improved tone discrimination performance for rats where the tone signaled reinforcement, and caused curare-like immobility and elevated rectal temperatures.

On the mechanism of development of astheno-autonomic disorders in chronic exposure to ultrahigh frequency fields

Ermakov EV · 1969

The study examines the mechanism of astheno-autonomic disorders from chronic ultrahigh frequency field exposure. It was published in Voen Med Zh volume 3 pages 42-4 in March 1969. The main subject heading covers human and animal analytics and toxicity.
