What is a common source of radiation found within the basement of homes?
radon 222 it comes form the cracks in the floor
Where are gfci outlets required?
GFCI receptacle's must protect any outlet that is within 6 feet of a water source, outside the home, in a garage, on a deck, in a sunroom, in a bathroom, unfinished basements, kitchens, & crawl spaces.
What type of device includes any point source that emits radiation without actively dispersing radioactive material across an area?
A point source device that emits radiation without actively dispersing radioactive material across an area is commonly referred to as a sealed radiation source. Such sources are contained within a sealed casing or structure that prevents the escape of radioactive material.
Is a microwave a source of heat energy?
Yes, a microwave is a source of heat energy. It heats food by using microwave radiation to agitate water molecules within the food, causing them to vibrate and generate heat.
What is the source of energy that drives convection within the Earth's atmosphere?
The source of energy that drives convection within the Earth's atmosphere is primarily solar radiation. The sun heats the Earth's surface unevenly, causing air to warm and rise in some areas and cool and sink in others, creating convection currents. This process is responsible for distributing heat and moisture throughout the atmosphere.
What is the strength and length of infrared radiation?
Infrared radiation has lower energy and longer wavelengths compared to visible light. Its strength and length can vary depending on the source, but typically falls within the range of 700 nanometers to 1 millimeter in wavelength.
Which type of devices includes any point source that emits radiation without actively dispersing radioactive material across an area?
Devices that include any point source that emits radiation without actively dispersing radioactive material across an area are considered sealed radiation sources. These sources are contained within a sealed container or device, preventing the spread of radioactive material.
What do visible lightinfrared radiationultraviolet radiation have in common?
They are all part of the electromagnetic spectrum, and examples of each can be observed within less than two octaves of frequency.
How hot is infrared radiation?
Infrared radiation is sometimes referred to as thermal radiation. The temperature of infrared radiation varies from object to object. All objects radiate infrared, even objects at room temperature and frozen objects.
Are living organisms a source of electromagnetic radiation?
Electromagnetic radiation is common in living organisms. One example is infrared radiation (heat) given off by warm bodies. And we know that critters like sharks can sense magnetic fields generated electromagnetically by other critters they are searching for.
Is radiation a physical hazard within the context of industrial hygiene practice?
Yes, within the context of industrial hygiene (occupational hygiene), radiation is a physical hazard.
What does lighting mean?
verb - to illuminate, or to set afire adjective - not heavy, or of lower caloric content adjective - of a color that is less dark noun - illumination, or a source of illumination noun (physics) - radiation : any frequency of electromagnetic radiation within the visible range for human beings. This constitutes a comparatively small range of possible electromagnetic energies. -- Briefly, light or light(s) means: 1) Electromagnetic radiation of a visible frequency or wavelength 2) A source of illumination 3) A source of fire or to set fire 4) A comparative shade of color or hue 5) Laundry that is not dark in color
