Radiotherapy to the head and neck causes temporary (or acute) side effects. Side effects can be mild or more severe, depending on the size of the area being treated and the length of your treatment.

Abstract: We present experimental results of a novel time-varying antenna to broadcast Very Low Frequency (VLF, 3-30 kHz) signals. The antenna consists of a 275-m long dipole interrupted with a ...

This is especially relevant in environments subject to radiation, in which materials, depending on their chemical and elemental composition, exhibit specific limitations. In this review, we summarize ...

With an impressive low profile of just 0.047 times the low-frequency wavelength, the prototype presents an efficient radiation pattern, achieved simultaneously together with a 12:1 impedance ...

Abstract: This work proposes a method for the synthesis of the shape of the whole radiation pattern at a single frequency using a partially reactively loaded antenna array. The method can be used for ...

particularly a rotating neutron star (like a pulsar), slows down its rotation due to the loss of rotational energy through magnetic dipole radiation. Through mapping the acceleration field of the ...

A CT scan exposes your body to some radiation. That involves a small amount of risk, and it’s important to understand the issues. A CT scan uses what’s called “ionizing” radiation.

When you have cancer, though, some cells start to divide way too fast. That's where radiation therapy can help. It uses high-energy particles to make tiny breaks in the DNA of cancer cells to ...

It also created two new bands of radiation around the planet, researchers report in the February JGR Space Physics. Earth is encircled by two donut-shaped bands of particles called the Van Allen ...
