That means lower energy bills and faster cooling. Also, your AC unit won’t need to work nearly as hard to cool it down. If the insulation in your attic stays cooler, your living space stays cooler. Second, insulation is made better by a radiant barrier. It will eventually heat up as nothing blocks that transfer of heat. First, insulation does nothing to defend against rising radiant heat levels in the attic.

Existing 3–4 inches of insulation: R38 to R49.

Existing 3–4 inches of insulation: R25 to R38.

Existing 3–4 inches of insulation: R25 to R30.

Here are some typical recommended home insulation R–values for wood-framed buildings per Energy Star: In fact, we’d go so far as to say that if you don’t have at least R40 in your attic, you should do that first-or at least budget and plan for it. What About Insulation? Or More Insulation? Bosch geothermal heating and cooling systems make a great example. Other technologies exist to help save energy as well. It even works in other applications as we recently installed radiant barrier in a shop. Radiant barrier products actually make your attic insulation work better. Your attic floor insulation is the second step which blocks conductive heat flow to the rooms below. Radiant barrier is the first step to block radiant heat coming in from the sun. That’s not cool by any means, but it’s a LOT cooler than what you get without the radiant barrier. Instead of your attic heating up to 160º F (no, we’re not joking, I’ve taken these measurements myself), your attic will stay at a toasty 100-110º F. But a large portion of it does-up to 95% or more. Now, we’ll be the first to tell you that not all of the heat bounces back. It keeps heating up because the heat energy is stored in the material, making it generate that heat back into the environment-in this case, the vehicle interior. It then hits the dash and that heats up as well.

Why is that? It’s because the very items inside your car, and your car itself, will literally radiate heat. The inside of your car feels like an oven-reaching temperatures much higher than the 100º outside. What happens when you park it out in the open when the ambient temperature hits 100º? You can understand why radiant barriers work simply by considering the best place to park your car. The Quick Explanation–Where Do You Park Your Car? Something heated up by radiant energy will eventually begin to emit its own heat in all directions. Radiant heat is energy (from the sun or any other source) that is transferred without making actual contact. It keeps an object from becoming energized by UV rays and radiating its own heat. The word more or less gives it away-a radiant barrier is anything that reflects heat back to the source. Radiation area monitors: Typically required when exposure rates are such that the exposure of an individual in the area could exceed institutional administrative controls specified by the facility RSO and/or the RSC.A radiant barrier blocks “radiating” UV heat that would otherwise penetrate and heat objects and spaces like the inside of your attic. ACCESSORIES: Hand switch with Flexible long cord enables the operator to keep from the Radiation area during exposure.9. Each radiation area shall be conspicuously posted with appropriate signs.Īluminum Filters 1.5 mm, can be operated from control panel through feather touch key.8. Employers shall be responsible for proper controls to prevent any employee from being exposed to ionizing radiation in excess of acceptable limits.3. Radiation area - Any area accessible to personnel, in which there exists radiation at such levels that a major portion of the body could receive in any one hour a dose in excess of five millirem or in any five consecutive days a dose in excess of 100 millirem.2.

Explain why an event with a SPFO that occurs in a Very High Radiation area merits a yellow finding.Īrea Surveys - Radiation area surveys are performed to assess ambient exposure levels in occupied areas in the vicinity of radiation sources (those stored, being handled, or in patients), to detect or localize contamination, and/or to find lost sources.
