Linear Energy Transfer. Farlex partner medical dictionary farlex 2012. It describes the action of radiationinto matter.
There is a mixture of primary and secondary particles with varying energies. It is specified by the differential d e d x in which d e represents the energy loss and d x represents the increment of path length. Linear energy transfer let the amount of energy per unit length lost by a particle or photon traversing a material.
Monte carlo track chemistry simulations were used to calculate the time dependent yields g values for the radical eaq h oh and molecular h2 h2o2 primary species formed in the low linear energy transfer let radiolysis of deaerated pure water h2o in the range of 1 ps to 1 ms between 25 and.
Since the energy reduction is component of the description let is a positive quantity. Linear energy transfer let is the energy transferred per unit length of the track. The term linear energy transferlet is used to indicate the average amount of energy that is lost per unit path length as a charged particle travels through a given material. The let is usually written as a function l t of the kinetic energy t of the particle and is conveniently expressed in units of kevµ where µ is 1 micron of path length.
