Electromagnetic (EM) radiation, on the other hand, has no mass and travels in waves. EM radiation can range from very low energy to very high energy, and we call this span the electromagnetic spectrum. Within the EM spectrum, there are two types of radiation -- ionizing and non-ionizing....
Mechanical sensors can detect far lower radiation levels in real time, rather than as a cumulative dose like the phytosensors detect. This makes mechanical sensors ideal for everyday monitoring of dangerous radiation within a power plant, while phytosensors are better suited to monitor the larger a...
A method of detecting, counting or otherwise measuring nuclear radiation includes the steps of exposing a diamond containing single substitutional paramagnetic nitrogen to the nuclear radiation to cause electrons or holes to be trapped at lattice imperfections within the diamond crystal structure, heating ...
When the collision with a star produces a vast amount of energy and light it is known as a quasar. This enormous event allows the array of radio telescopes to detect the radiation, locate the event horizon and finally form a picture of a black hole’s shadow. This planetary collaboration ...
Synchrotron radiation generated by a charged particle with relativistic speed deflected on circular paths is a well-known physical phenomenon. However, in recent years this principle of radiation generation was further developed to generate picosecond pulses in the terahertz frequency range, thus closing ...
Quantitative cytogenetic analysis of structural chromosome aberrations in human peripheral blood lymphocytes is widely used as an assay to detect and quantify exposure to a variety of clastogens. Unstable chromosome rearrangements, dicentric chromosomes (dic) and centric ring chromosomes (centric r), are...
Ionization Detectors: Ionizing Radiation Ionization smoke detectors use an ionization chamber and a source of ionizing radiation to detect smoke. This type of smoke detector is more common because it is inexpensive and better at detecting the smaller amounts of smoke produced by flaming fires. Insi...
When he did this, he was able to detect electrons being emitted from the surface. This was Einstein's explanation: If the energy in light comes in bundles, then one can think of light as containing tiny lumps, or photons. When these photons strike a metal surface, they act like billiard...
Research articles based on the Surveillance, Epidemiology, and End Results (SEER) (not SEER-Medicare) that had been published in journals from 1998 to 2022 searched by PubMed. The joinpoint analysis program chose the most suitable loglinear regression model to detect calendar years (known as “...
Insertional and terminal translocations are difficult to detect using traditional cytological or genetic methods but they are readily revealed when ascus patterns are examined. Insertional and terminal rearrangements generate a class of aneuploid progeny that carry a duplication but no deficiency, and this...
