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

ForensicsSee Stopping power.

Nuclear physics

The reduction of kinetic energy of an ionising particle as it passes though a material of a particular density.

## lin·e·ar en·er·gy trans·fer

**(LET)**(lin'ē-ăr en'ĕr-jē trans'fĕr)

Rate at which a charged particle deposits energy as it travels through matter.

## lin·e·ar en·er·gy trans·fer

**(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

in a line.

**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**

see 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.
