Comments on radiation dosimetry and linear energy transfer
Sozial- und Pr�ventivmedizin SPM, 1991The quantification of the physical effects of ionizing radiation in human tissue is the basis of risk assessment. This quantification results from determination of kerma or absorbed dose. The procedure for the absolute determination of absorbed dose with an ionization chamber is discussed. The biological effects of ionizing radiation are dependent, not

Linear Energy Transfer and Track Structure
1993Publisher Summary This chapter discusses track structures and linear energy transfer. There are two types of energy dissipation of heavy ions—nuclear and electronic stopping. Nuclear stopping has high RBE values and predominates at extremely low specific energies of a few kiloelectronvolts per mass unit, corresponding to the last micrometers of the ...

Irradiation of Atactic Polystyrene: Linear Energy Transfer Effects
The Journal of Physical Chemistry B, 2008Atactic glassy polystyrene (PS) has been irradiated in anoxic conditions by electron and ion beams. The induced modifications were followed, in situ, by Fourier transform infrared spectroscopy (FTIR). In-film modifications and hydrocarbon gas release were followed.

Measurements of Neutron Dose as a Function of Linear Energy Transfer
Radiation Research, 1955Recent developments in radiobiology have created a need for a more detailed description of physical exposure conditions. In particular, the relative biological effectiveness (RBE) is believed to be related to the linear energy transfer (LET) (1) of the charged particles traversing irradiated tissues. In fact, permissible exposure to ionizing radiations

A Spatially Restricted Linear Energy Transfer Equation
Radiation Research, 1992An analytical expression is developed for calculating the average energy deposited by an ion in a volume with dimensions less than the range of the secondary electrons produced. The expression is obtained by including two additional terms in an energy-restricted linear-energy-transfer equation. The usual energy-restricted expression accounts for energy

Non-linear dynamics and energy transfer
Journal of Molecular Structure, 1986Abstract Non-linear dynamics is mostly concerned with coupled anharmonic oscillators, a common situation in the classical description of molecule dynamics. Non-linear systems are in general not integrable, but for small enough energy or couplings most trajectories are quasiperiodic (KAM theorem).

Modeling Framework for Contactless Energy Transfer Systems for Linear Actuators
IEEE Transactions on Industrial Electronics, 2013This paper presents a semi-analytical modeling framework to evaluate the performance of a contactless energy transfer system which consists of multiple primary windings and a linear moving secondary winding. The modeling framework combines steady-state and electromagnetic analysis and is able to deal with different winding configurations, consisting of

A Linear Energy Transfer Effect in the Radiolysis of Cyclohexane
Nature, 1964PREVIOUS experiments1,2 with aliphatic hydrocarbons have shown little dependence of product yields on the type or incident radiation over the range of linear energy transfer (LET) used, although substantial variations have been reported for aromatic3,4 and unsaturated5 substances.

Limitations of the Concept of Linear Energy Transfer (LET)
Radiology, 1956Variations in the relative biological effectiveness of ionizing radiations are commonly attributed to differences in specific ionization or linear energy transfer (LET). The implication has been that for each radiation field there exists one definite distribution of dose in LET (LET spectrum) that may be computed from an analysis of the existent ...

Electronic Energy Transfer in Linear Polymer Chains
High Energy Chemistry, 2002The effect of the size of a polymer molecule and the character of the motion of its units in solution on the luminescence kinetics of chromophores attached to the polymer chain was studied.
