On calculation of the average linear energy transfer for radiobiological modelling. [PDF]
Biomed Phys Eng Express, 2021 Abstract Applying the concept of linear energy transfer (LET) to modelling of biological effects of charged particles usually involves calculation of the average LET. To calculate this, the energy distribution of particles is characterized by either the source spectrum or fluence spectrum.

Linear energy transfer-independent calibration of radiochromic film for carbon-ion beams [PDF]
Physics and Imaging in Radiation Oncology, 2022 For carbon-ion beams, radiochromic film response depends on the dose and linear energy transfer (LET). For film dosimetry, we developed an LET-independent simple calibration method for a radiochromic film for specific therapeutic carbon-ion beams.
