intensity of radiation

The intensity of radiation increases rapidly in the direction you indicate.

"The integration process requires a certain very low intensity of radiation," he explained.

From these colors scientists could determine the intensity of radiations to the year 1.

The number of different intensities of radiation the sensor is able to distinguish.

The intensity of radiation scales as , where is the number of poles in the magnet array.

To first approximation shielding reduces the intensity of radiation exponentially depending on the thickness.

The intensity of radiation was logarithmically proportional to the Lorentz factor of the particle.

Air coming in the pierced walls that closed off unknown winding passages showed an intensity of radiation that made Belmont whistle softly.

The Compton-Getting effect is an apparent anisotropy in the intensity of radiation or particles due to the relative motion between the observer and the source.

An isotropic radiator is a theoretical point source of electromagnetic or sound waves which radiates the same intensity of radiation in all directions.

Dividing the spectrum into many bands, multispectral is the opposite of panchromatic, which records only the total intensity of radiation falling on each pixel.

The ATR allows scientists to place a great variety of materials in an environment with specified intensities of radiation, temperature and pressure.

Not only does it detect the presence and intensity of radiation, it also draws a map of the surrounding area and shows you where the emission is.

This is a thermodynamic technique that relies on the measurement of temperature using a thermometer or of intensity of radiation using a bolometer.

Methods for measuring the amount or intensity of radiation had not been developed, and the doses to which different patients were exposed probably varied from the imperceptible to the lethal.

The cloud first passed over the observatory between 10 and 15 April, and produced a pronounced dip in the measured intensity of radiation from the solar disc (Figure 1).

Hence, the intensity of radiation passing through any unit area (directly facing the point source) is inversely proportional to the square of the distance from the point source.

Ideally the parent isotope will have a sufficiently long half-life to remain useful, but will also have a sufficient decay rate to supply the required intensity of radiation.

For instance, the thinnest walls on the sides of a 4 HVL tungsten collimator 0.52" thick will reduce the intensity of radiation passing through them by 88.5%.

The intensity of radiation in the cores of supermassive stars could be so great, they said, that pairs of electrons and their antimatter opposites, positrons, would be created.

Experiments on the biological effects of radiation were similarly hampered by the problems of measuring the intensity of radiation and the proportion of it absorbed by living tissues.

The exponential growth in intensity of radiation passing through a maser cloud continues as long as pumping processes can maintain the population inversion against the growing losses by stimulated emission.

Spectral measurements can be graphed to represent the intensities of radiation at different wavelengths, and the resulting graphic spikes reveal the amounts and types of chemicals producing the radiation.

A material's half-value layer (HVL), or half-value thickness, is the thickness of the material at which the intensity of radiation entering it is reduced by one half.

The intensity of radiation within the belts is such that irradiation would quickly darken (within 100,000 years) any methane trapped in the icy surfaces of the inner moons and ring particles.
