Those coatings qualified as Interior Radiation Control Coatings must show a thermal emittance of 0.25 or less. This means that an IRCCS will block 75% or more of the radiant heat transfer. These low "E" coatings were originally developed in 1978 at the Solar Energy Corporation (SOLEC) in Princeton, New Jersey for use in tubular evacuated solar ...
In radiotherapy, radiation treatment planning (RTP) is the process in which a team consisting of radiation oncologists, radiation therapist, medical physicists and medical dosimetrists plan the appropriate external beam radiotherapy or internal brachytherapy treatment technique for a patient with cancer.
The solar reflectance of the paints arises from optical scattering by the dielectric pigments embedded in the polymer paint resin, while the thermal emittance arises from the polymer resin. However, because typical white pigments like titanium dioxide and zinc oxide absorb ultraviolet radiation, the solar reflectances of paints based on such ...
While some of the surface's solar reflectance is lost in the visible light spectrum, colored PDRCs can still exhibit significant cooling power, such as a coating by Zhai et al., which used a α-Bi 2 O 3 coating (resembling the color of the compound) to develop a non-toxic paint that demonstrated a solar reflectance of 99% and heat emissivity of ...
Solar induced heat (direct sunlight) is reflected from the surface as well as heat (winter months) that is migrating through the wall outward toward the colder outside air. A "thermal Image" or infra-red photograph will clearly show the reduction of winter time heat loss from a home through areas that have been painted with a true "insulative ...
The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).
External beam radiation therapy (EBRT) is a form of radiotherapy that utilizes a high-energy collimated beam of ionizing radiation, from a source outside the body, to target and kill cancer cells. The radiotherapy beam is composed of particles, which are focussed in a particular direction of travel using collimators. [ 1 ]
It has also been used with Stereotactic Body Radiation Therapy to assist with the initial set-up and detect intrafraction patient motion throughout treatment. [3] For stereotactic surgery , SGRT allows a frameless system to be used to monitor the surface of the patient within an open-face immobilization mask.
