|April 28, 1989
Resumen
El espectrómetro de rayos gamma (GRS) detectó eventos transitorios inusuales de alta energía de reactores que orbitan la Tierra, no fenómenos naturales. Estos eventos plantean riesgos para las observaciones cósmicas y de la posible reentrada de satélites.

Sus antecedentes:
- El espectrómetro de rayos gamma (GRS) del satélite Solar Maximum Mission (SMM) ha monitoreado el sol desde principios de la década de 1980.
- Las observaciones del GRS incluyen erupciones solares, explosiones cósmicas de rayos gamma y electrones del cinturón de radiación.
Objetivo del estudio:
- Identificar y caracterizar una nueva clase de eventos transitorios de alta energía detectados por el GRS.
- Para determinar el origen y las posibles implicaciones de estos eventos anómalos.

- Categoría de eventos transitorios basados en la duración, las firmas de energía (0.511-MeV línea de aniquilación, eventos de partículas, continuo de banda ancha), y la ocurrencia temporal.
Principales resultados:
- Detección de una nueva clase de eventos transitorios de alta energía, distintos de los fenómenos solares o cósmicos conocidos.
- Se observó un aumento significativo en las tasas de eventos a partir de febrero de 1987.
- La evidencia sugiere que estos transitorios se originan en reactores en satélites que orbitan la Tierra, no en fuentes naturales.
Conclusiones:
- Los transitorios detectados son probablemente artificiales, originados en reactores terrestres en órbita.

02:39Emission Spectra
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.
01:22Atomic Emission Spectroscopy: Instrumentation
The instrumentation of atomic emission spectrometry (AES) involves various components, including atomization devices that convert samples into gas-phase atoms and ions. There are two main types of atomization devices: continuous and discrete atomizers. Continuous atomizers, like plasmas and flames, introduce samples in a constant stream, while discrete atomizers inject individual samples using syringes or autosamplers. The most common discrete atomizer is the electrothermal atomizer.
01:14UV–Vis Spectrometers
The absorbance of UV and visible (UV–visible) radiations is measured using a UV–visible spectrophotometer. Deuterium lamps, which emit UV radiation, and tungsten lamps, which produce radiation in the visible region, are used as light sources in UV–visible spectrophotometers. A monochromator or prism is used for diffraction grating, i.e., to split the incoming radiation into different wavelengths. A system of slits is used to focus the desired wavelength on the sample cell. Samples for...
01:29Atomic Emission Spectroscopy: Lab
AES is a powerful analytical technique, especially effective when used with plasma sources, producing abundant spectra in characteristic emission lines. The Inductively Coupled Plasma (ICP), in particular, yields superior quantitative analytical data due to its high stability, low noise, low background, and minimal interferences under optimal experimental conditions. However, newer air-operated microwave sources are emerging as promising alternatives that could be more cost-effective than...
01:20Atomic Emission Spectroscopy: Overview
Atomic emission spectroscopy (AES) is an analytical technique used to determine the elemental composition of a sample by analyzing the light emitted from excited atoms. In AES, atoms in a sample are excited to higher energy levels by thermal energy from high-temperature sources, such as plasma, arcs, or sparks. When these excited atoms return to lower energy states, they emit light at specific wavelengths characteristic of each element. The resulting atomic emission spectrum, which consists of...
01:16UV–Vis Spectroscopy: Molecular Electronic Transitions
In Ultraviolet–Visible (UV–Vis) spectroscopy, the absorption of electromagnetic radiation is used to probe the electronic structure of molecules. This technique provides insights into molecular electronic transitions, particularly the movement of electrons between different molecular orbitals. Radiation is absorbed if the energy of the electromagnetic radiation passing through the molecule is precisely equal to the energy difference between the excited and ground states. During this process,...
