Related to linear energy transfer: Stopping power

lin·e·ar en·er·gy trans·fer (LET),

the amount of energy deposited by radiation per unit length of travel, expressed in keV per micron; protons, neutrons, and α particles have much higher LET than gamma or x-rays. A property of radiation considered in radiation protection. See: relative biologic effectiveness.

linear energy transfer (LET)

the rate at which energy is transferred from ionizing radiation to soft tissue, expressed in terms of kiloelectron volts per micrometer (keV/μm) of track length in soft tissue. The LET of diagnostic x-rays is about 3 keV/μm, whereas the LET of 5 MeV alpha particles is 100 keV/μm.

mass stopping power

See Stopping power.
Nuclear physics
The reduction of kinetic energy of an ionising particle as it passes though a material of a particular density.

(LET) (lin'ē-ăr en'ĕr-jē trans'fĕr)
Rate at which a charged particle deposits energy as it travels through matter.

(LET) (lin'ē-ăr en'ĕr-jē trans'fĕr)
Rate at which a charged particle deposits energy as it advances.

linear energy transfer (LET),

n the linear rate of loss of energy by an ionizing particle traversing a material medium.

linear assessment
a method of expressing an assessment result as a score out of a possible perfect score of 10, or some other number. Used in body condition scoring, showring judging of conformation.
linear dodecyl benzene sulfonic acid teat dip
linear energy transfer
expresses the quality of electronic radiation. It is concerned with the spatial distributions of energy transfers which occur in the tracks of particles as they penetrate matter.
linear program
a management program used to determine the best mix of ingredients or services to be used in a particular situation to maintain the highest level of productivity or profitability or other similar parameter.
linear regression
statistical method used to study the relationship between independent and dependent variables when the dependent variable consists of continuous data.
linear score
for somatic cell counts in milk (SCCs) convert SCC logarithmically from cells per milliliter to a linear score from 0-9. The linear score has a straight line, inverse relationship with milk yield. An increase of one in the linear score is associated with a 400-pound decrease in lactation milk yield or a 1.5 pound drop in daily yield.
