Luminescent radio frequency radiation dosimetry

Bioelectromagnetics, 1999
Thermoluminescent dosimetry has been the industry standard for ionizing radiation dosimetry because it is inexpensive, sensitive, and accurate. No such system exists for radio frequency radiation. This paper describes the state of the art of efforts toward developing such a system.

Radio and microwave radiation and experimental atherosclerosis

Atherosclerosis, 1976
The effect of radio and microwave radiation on dietary atherosclerosis of rabbits was tested. 16 New Zealand white rabbits were exposed to microwave (2.45 GHz) radiation at a power density of 20--30 mW/cm2 for 4 h a day, 5 days a week for 8 to 10 weeks.

Radio frequency radiation (RFR) from radio antennas

2003 IEEE International Symposium on Electromagnetic Compatibility, 2003. EMC '03., 2003
For the last 30 years, biological effects of non-ionizing radiation (NIR: 0-300 GHz) has got the top position in the scientific area, since a large population of the people are exposed to these fields. In this study, we evaluated the radio frequency radiation (RFR) at a pilot region located in Yenimahalle Sentepe Dededoruk Hill, in Ankara, Turkey ...

Weakly radiating radio pulsars

Astronomy Letters, 2004
We analyze the statistical distribution of weakly radiating pulsars, i.e., radio pulsars that have passed to the stage of an orthogonal rotator during the evolution of the inclination angle X. We discuss in detail the factors that lead to a significant reduction in the energy losses for this class of objects.

Cosmic Radiation and Radio Stars

Physical Review, 1950
The normal radio wave emission from the sun amounts to 10-17 of the heat radiation, and increases during bursts1 to as much as 10-13. If a radio star, e.g., the source in Cygnus, is situated at a distance of 100 light years, its radio emission is of the order of 10-4 of the heat radiation of our sun. It is very un-likely that the atmosphere of any star

Radio Continuum Radiation

1992
Most galaxies are continuum radio sources and M31 is no exception. It is what radio astronomers classify as a normal galaxy, though, not a radio galaxy, as its radio luminosity is moderate. The spectrum of its radio radiation shows that the sources of this radiation are both thermal and non-thermal.

Radio Radiation from the Supergalaxy

Nature, 1953
IN March 1953, during a survey of the background radiation at 250 Mc./s. with the Ohio State radio telescope1,2, a low-intensity source was observed near R.A. 13h. extending at least from Dec. − 15° to + 15°. Further measurements indicate that the maximum or ridge line of this source extends along the dashed curve shown in the accompanying figure. Near

Solar radio-frequency radiation

Journal of the Institution of Electrical Engineers, 1950
The paper attempts to survey research on solar radio-frequency radiation, or solar noise, to early 1948. After an introduction concerned with history and units for specification of intensity, the observed characteristics of solar noise in the wavelength range from 1 cm to some metres are described.

Characteristics of cosmic radio radiation

Physics Today, 1961
Cosmic radio radiation is radiation of extraterrestrial origin in the radio-frequency portion of the electromagnetic spectrum. Such radiation was discovered by Karl Jansky of Bell Telephone Laboratories in 1932 on a wavelength of 14.6 m. While studying the direction of arrival of the atmospheric disturbances which interfere with the transatlantic short-
