In news:

Lang and Randall believe the radio frequency (RF) radiation emitted from the meter-reading devices causes health problems and argued that Clarkfield residents should not be forced into accepting the new technology.
An alternative to gasses, radiation or carbon-producing thermal techniques, Radio Frequency Co. Macrowave Ultra-Series pasteurization systems apply a high-frequency electric field to control pathogens in food.
(More familiar forms of this radiation include radio, light and X -rays.
Hardin stated that "X-rays, like radio waves and visible light … do not involve neutrons at all, and are therefore called non-ionizing radiation" ("A Scream," Mailbox, March 31).
Do people not realize how much radiation they get from the sun everyday (including radio waves).
A a strong solar radiation storm is expected to cause more trouble with electrical grids, satellite and radio signals.
Summer means sunshine and here are a couple of neat projects that you can quickly build for exploring two different properties of the sun: radio spectrum analysis and solar radiation measurement.
The American Academy of Environmental Medicine has called for a moratorium on smart meters in homes and schools, based on the documented health hazards of radio frequency radiation from these tools.
Hardin stated that " X-ray s, like radio waves and visible light … do not involve neutrons at all, and are therefore called non-ionizing radiation" ("A Scream," Mailbox, March 31).

In science:

The radiation that is occasionally emitted from nonrelativistic shocks is restricted to the radio are not retarded from flow speed to rest) and, third, because of the low ‘emission measure’ EM = (cid:82) dr3∆N 2 wave range.

But these are correlated with broadening of the harmonic radio radiation towards lower frequencies.

Moreover, they might be responsible for the electromagnetic radiation generated in the shock ramp, a process that has been observed in solar and interplanetary type II radio bursts but never found a convincing explanation by any known mechanism.

The X-ray/TeV flux correlation (see Fig. 1) suggests that the emitting particles are electrons radiating synchrotron emission in the radio to X-ray band and inverse Compton emission in the gamma-ray band.

It is, however, important to note that not every cluster shows central radio activity, and that the steep dependence of the radiative cooling function on density makes it difficult to stabilize cooling flows at all radii.

The CN is a source of diffuse radio, optical and X-ray radiation associated with a Supernova explosion observed in 1054 A.D.

The radio loudness is a measure of the number of high energy synchrotron-radiating electrons.

Radio detectors look for the coherent Cherenkov radiation produced by excess of electrons in neutrino induced showers in dense media (Askaryan effect) such as ice and the lunar regolith [100], [101].

Most importantly, the frequencies of the EM radiation are well outside the range of existing radio observations and hence direct observation is highly unlikely.

Since mini radio lobes with LS ∼ 10 pc are closely located near the AGN core, the lobes are expected to be in dense external radiation fields (Fig. 1).
Hadronic gamma-ray emission from extragalactic mini radio lobes
The typical lifetime is few Gyr for electrons with E ≈ 100 MeV but it is much shorter, about 108 yr, for electrons with E ≈ few GeV, that are those emitting synchrotron radiation in the radio band.
Cosmic rays and diffuse non-thermal emission in galaxy clusters: an introduction
Because the diffusion time on halo scales (Mpc) of GeV electrons is much longer than their radiative life-time (Fig.1), mechanisms of in-situ (spatially distributed) acceleration/injection of electrons are necessary to explain radio halos (Jaffe 1977).
Cosmic rays and diffuse non-thermal emission in galaxy clusters: an introduction
In Fig. 2 we show the radiation produced by the trapped and escaping CRs, along with the observations of SNR J1713 at radio (Acero et al. 2009), X-ray (Suzaku; Tanaka et al. 2008), GeV (Fermi-LAT; Abdo et al. 2011), and TeV energies (HESS; Aharonian et al. 2007).

They are also an order of magnitude more luminous than the radio nebula around SS 433 (Dubner et al. 1998), which well matches the relative values of radiative and mechanical core power in those sources.
Ultraluminous X-ray Sources in the Chandra and XMM-Newton Era
They showed that the observed radio emission is synchrotron radiation of electrons, accelerated in the forward shock of the SN explosion, while inverse Compton (IC) scattering of these electrons produced X-rays.
