attenuation factor

Related to attenuation factor: attenuating

attenuation factor

The ratio of the incident radiation dose or dose rate to the radiation dose or dose rate transmitted through a shielding material. This is the reciprocal of the transmission factor.

FOURTH AMENDMENT FLAGRANCY: WHAT IT IS, AND WHAT IT IS NOT

Let us define the attenuation factor [alpha] = Im[[V.sup.2]]/[[absolute value of V].sup.2] (where V is a complex velocity [7]) that corresponds to the definition of the quality factor Q = 2[pi]E/[DELTA]E, where E is the wave energy and [DELTA]E is the energy lost per cycle due to attenuation [9].

The [mu] factor is obtained from the energy registered for the study in the XCOM database [44], which exists for concrete and lead, where mass transmission coefficient is obtained and, hence, the attenuation factor.

On the other hands, due to the frequency dependence of attenuation (high attenuation factor for high frequency components) , number of high frequency AE due to fiber breakage (550-650kHz) is drastically reduced for the results of 20 and 30 mm propagation lentgh (Fig.
