Radiation devices

Density Gauges These are used to measure the density or suspended solids content of the feed and underflow streams. Gamma radiation devices are the most commonly used for automatic control, but ultrasonic devices are effective in the lower range of slurry density. Marcy pulp density scales are an effective manually operated device. A solids mass flow indication is usually obtained by combining a density gauge output with the output from a flowmeter. 

Every electronic system has some level of electromagnetic radiation associated with it. If this level is strong enough to cause other equipment to malfunction, the radiating device will be considered a noise source and usually be subjected to shielding regula-... 

The main characteristic of non-guided radiation devices is that the recognition element or the chemical membrane is not physically integrated in any waveguide structure. Variations of the membrane optical properties lead to variations of the transmission of a non-guided light beam (Fig. 4a). 

An immersible transducer is a radiating device accommodated in a housing which can be submerged in a liquid bath to energize the liquid and produce cavitation. An immersible transducer placed in a still tank therefore turns that tank into an ultrasonic cleaner. The immersible transducer is, in effect, a standard tank (turned inside out) with the radiating surface on the outside and the transducers on the inside. 

Large band gap UV radiation devices for sterilization, light sources for UV microscopes and displays... 

Dielectric resonator antennas (DRAs) constitute an important family of radiation devices, since they exhibit sufficient directivity and gain, while their small size enables the handling of multipath signals [19—22]. 

The receiver system consists of a preamplifier (Radiation Devices model BBA-1P, bandwidth 3-500 MHz at 15 dB gain and 3 dB noise), a 10 MHz amplifier (F+H Instruments mixer-amplifier, model 39 A/M), and a phase detector (F+H Instruments phase detector 1-30 MHz). 

Thermal plasma light sources are effective radiation devices in generating short-wavelength (UV and VUV) radiation (Protasov, 2000). The emission spectram of the absolute blackbody with temperatme T has a radiation maximum at the frequency max ...

BF3 detectors tree occasionally used based on the B(n, a) Li reaction. BF3 detectors are less sensitive to gamma radiation fields but are less efficient. Recently, solid-state neutron radiation devices with boron carbide diodes have been developed, which demonstrate very promising potential for future applications such as miniaturized handheld neutron detection devices.

Unintentional (incidental) radiating devices - Devices that radiate radio frequencies but is not considered their primary function. 

Restricted radiating devices - Devices that intentionally use electromagnetic radiation for purposes other than communication or data transfer (i.e. operating systems, wireless microphones, etc.). 

Ammunition technicians of the Army s Royal Logistics Corps (RLC) deal with improvised explosive devices (lEDs) and have expertise in chemical, biological and radiation devices (including dirty bombs ). 

Various types of elaborate burner systems for the production of more radiation and a better distribution of heat in the combustion chamber have been suggested. Some of these consist of a furnace floor of small gas jets and although they perform well, they are expensive. A successful artificial-radiation device is the muffle burner of the Alcorn Combustion Company. In this burner the gas fuel is fired through a long muffle which may extend along the entire length of the floor of the still. The muffle becomes hot and acts as a radiator, and the flame that issues from the end of the muffle also contributes to the radiation.
