INDIRECT RADIATION [8 records]

Record 1 2025-06-20

English

Subject field(s)
  • Visual Disorders
CONT

Solar maculopathy(SM) appears as a consequence of direct or indirect visual exposure to sunlight, being caused by light radiation and its photochemical effects. It is characterized by a bilateral decrease in visual acuity(VA) accompanied by central scotoma, with the dominant eye being more commonly affected.

French

Domaine(s)
  • Troubles de la vision
CONT

La maculopathie solaire est un phototraumatisme rétinien lors de l'exposition solaire. Elle constitue une cause inhabituelle de baisse de l'acuité visuelle [...]

Record 2 2022-12-05

English

Subject field(s)
  • Climate Change
  • Pollutants
DEF

The effect of anthropogenic aerosols on the radiative fluxes at the top of the atmosphere ... and at the surface and on the absorption of radiation within the atmosphere.

CONT

Aerosol forcing is divided into two components : direct effects, mainly from absorbing or scattering incoming solar radiation, and indirect effects from aerosol interactions with clouds.

French

Domaine(s)
  • Changements climatiques
  • Agents de pollution
CONT

Du fait de toutes les incertitudes évoquées [...] (composition, dimensions, répartition), le forçage radiatif des aérosols est beaucoup moins bien estimé que celui des gaz à effet de serre.

Record 6 2001-09-27

English

Subject field(s)
  • Atomic Physics
  • Electromagnetic Radiation
  • Soil Science
CONT

The method by which incident radiation interacts with the medium to cause ionization may be direct or indirect. Electromagnetic radiations(X rays and gamma photons) are indirectly ionizing; that is, they give up their energy in various interactions with cellular molecules, and the energy is then utilized to produce a fast-moving charged particle such as an electron. It is the electron that then secondarily may react with a target molecule. Charged particles, in contrast, strike the tissue or medium and directly react with target molecules, such as oxygen or water. These particulate radiations are directly ionizing radiations.

CONT

The third step is to fuse two tritium nuclei into one helium and two proton products. The end result of fusing four hydrogen nuclei (protons) is one helium nucleus, and two gamma ray photons, and two electron neutrinos, and kinetic heat energy.

OBS

Gamma rays: A very penetrating electromagnetic radiation emitted from a nucleus of an atom during radioactive decay. Radiation: An emission of energy in the form of photons (gamma, x-rays) or particles (alpha, beta, positron, neutron radiation). Photon: A type of radiation in the form of an electromagnetic wave, having zero mass and zero charge.

Key term(s)
  • gamma photon

French

Domaine(s)
  • Physique atomique
  • Rayonnements électromagnétiques
  • Science du sol
CONT

Les photons gamma très pénétrants permettent de réaliser de véritables radiographies des matériaux les plus denses. Cette technique [gammamétrie] est appliquée depuis quelques années à la détermination de la densité et de l'humidité des sols.
