Do radiation detectors pick up all of the radiation in the air?

Not necessarily.
Different kinds of radiation detectors pick up different kinds of radiation. Also some radiation is of so little importance, that detectors are not designed to pick it up. An example here is UV light, which is actually low level ionizing radiation.
One more thing: Radiation doesn't require air to travel. A quick example: The sun's radiation reaches earth, yet there is no air in space for it to travel through.

Do smoke detectors have to be on a desginated circuit in bedrooms?
Putting smoke detectors on a designated circuit is a good design policy. One of the features of a designated design is that the smoke detectors can be all looped together. The smoke detectors of today have a third terminal where if one detector trips all of the detectors on the circuit have the ability, if connected, to alarm. All of the detectors are wired with a 3 conductor #14 cable. The black and white wires are used for power to the detector and the third red wire is used on the third terminal to alarm all of the detectors on the circuit when one smoke detector trips. With all detectors in an alarm mode it is hard not to hear or sleep through any emergency because of closed doors blocking the sound. Using this method of connection it is recommended a detector in each bedroom and above the stairwell between floors. Keep away from the kitchen area or the whole house will know when someone burns the toast.
How is the earths energy tansferred between the earths surface and the atmosphere?
Heat transfer within the atmosphere occurs via all three modes of heat transfer:Conduction - as the air contacts existing heat sources. These might be surfaces that have been heated previously viaabsorptionof solar radiation or from chemical reactions Convection - as warm air mixes with cold air as air currents move the air around and as buoyancy effects cause warm air to rise and cooler air to sink. Radiation - much of the air is composed of heat absorbing molecules such as water vapor. Solar radiation is absorbed by these molecules, causing them to warm up.
Do all molecules absorb infrared radiation?
No all molecules do not absorb infrared radiation. Some of them do.
Does solar radiation contain a complete spectrum of all forms of electromagnetic radiation?
Yes it does. It contains all the forms of radiation, but 99% of its energy is carried by radiation with wavelengths between 278 and 4600 nm, with the maximum at 4720 nm.
What percent of radiation is absorbed?
The radiation that are absorbed are not all useful. Only the harmful ones are.
Which isotopes are used in smoke detectors?
Americium (241) is used in smoke detectors that use "ionizing radiation" to detect changes in the air. Other types of detectors use photo-electric sensors based upon a variety of photo-sensitive chemicals.
What is Japan radiation?
Radiation is when nuclear leaks into the air and you inhale it it hurts you and can kill you. You experience radiation all the time! In x-rays! But the radiation in those are so less that it can't hurt you.
Do air cooled engines cool by conduction?
No, all engines cool by radiation.
What are sonic detectors?
Sonic detectors pick up sound waves and motions When things move, they often create changes in surrounding Read more: How Does a Sonic Motion Detector Work? | eHow.com http://www.ehow.com/how-does_4564490_sonic-motion-detector-work.html#ixzz1R9OT0diL not all written by me
What gives off electromagnetic radiation?
Many things give off electromagnetic radiation. Cell phones, the body, x-rays, and supposedly ghosts and spirits. EMF detectors (or electro-magnetic-field detector) are also supposed to pick up electromagnetic radiation given off by anything it's pointed at.
What is the natural way to detect radioactive radiation?
The ocean,the mountains,the air and our food all expose us to small ammounts of natural radiation.
Can radiation and convection and conduction be mixed?
i think it can or can not be mixed from all the air and hot heat
What is all around you you can touch it kick it breathe it but cant pick it up?
Air
Describe the way in which all machanism of heat transfer are involved in hearting the air?
Convection, conduction, and radiation
In what states are radar detectors legal?
Radar detectors are legal to use for all non-commercial vehicles in 49 states. Washington, DC and Virginia are the only two states that radar detectors are banned in the United States. Radar detectors used in commercial vehicles are illegal.
Why does the moon look like its is a different color?
the pollution in the air makes mostly all the light radiation reflect all some light
Can anyone give me a list of about 12 places that heat travels and whether it's by convection conduction or radiation?
1. From the sun to the earth, radiation 2. Heating lamp to you, radiation 3. You touching a hot stove, conduction 4. Heater blowing hot air, convection 5. Why the air heats up during the morning radiation from the ground, which is heated by radiation from the sun. That's all I could think of on the top of my head.
