  2. Biological effects of radiation on the epigenome - Wikipedia

    en.wikipedia.org/wiki/Biological_effects_of...

    Radiation exposure through ionizing radiation (IR) affects a variety of processes inside of an exposed cell. IR can cause changes in gene expression, disruption of cell cycle arrest, and apoptotic cell death. The extent of how radiation effects cells depends on the type of cell and the dosage of the radiation.

  3. Electromagnetic absorption by water - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_absorption...

    Liquid water and ice emit radiation at a higher rate than water vapour (see graph above). Water at the top of the troposphere, particularly in liquid and solid states, cools as it emits net photons to space. Neighboring gas molecules other than water (e.g. nitrogen) are cooled by passing their heat kinetically to the water.

  4. Cell culture - Wikipedia

    en.wikipedia.org/wiki/Cell_culture

    Cell culture is a fundamental component of tissue culture and tissue engineering, as it establishes the basics of growing and maintaining cells in vitro. The major application of human cell culture is in stem cell industry, where mesenchymal stem cells can be cultured and cryopreserved for future use. Tissue engineering potentially offers ...

  5. Penetration depth - Wikipedia

    en.wikipedia.org/wiki/Penetration_depth

    The penetration depth of X-rays in water as function of photon energy. Penetration depth is a measure of how deep light or any electromagnetic radiation can penetrate into a material. It is defined as the depth at which the intensity of the radiation inside the material falls to 1/ e (about 37%) of its original value at (or more properly, just ...

  6. Radio propagation - Wikipedia

    en.wikipedia.org/wiki/Radio_propagation

    Radio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another in vacuum, or into various parts of the atmosphere. [1]: 26‑1 As a form of electromagnetic radiation, like light waves, radio waves are affected by the phenomena of reflection, refraction, diffraction, absorption, polarization, and scattering. [2]

  7. Cell survival curve - Wikipedia

    en.wikipedia.org/wiki/Cell_survival_curve

    The shoulder of a low LET dose cell survival curve represents the point in which low doses of radiation do not diminish cell’s survivability to a point where an accumulation of said low dosages can cause a loss of cell reproduction. Some damage, fittingly, is thus dubbed “sublethal damage”.

  8. Effects of ionizing radiation in spaceflight - Wikipedia

    en.wikipedia.org/wiki/Effects_of_ionizing...

    On the other hand, active radiation shielding methods is an emerging technology which is still far away in terms of testing and implementation. Even with the simultaneous use of active and passive shielding, wearable protective shielding may be useful, especially in reducing the health effects of SPEs, which generally are composed of particles ...

  9. Linear energy transfer - Wikipedia

    en.wikipedia.org/wiki/Linear_energy_transfer

    Diffusion cloud chamber with tracks of ionizing radiation (alpha particles) that are made visible as strings of droplets. In dosimetry, linear energy transfer (LET) is the amount of energy that an ionizing particle transfers to the material traversed per unit distance.
