An analytical approximation of proton Bragg curves in lithium fluoride for beam energy distribution analysis

Nuclear Instruments and Methods in Physics Reseach B, 2019
An analytical model that approximates Bragg curves due to protons in water is extended to lithium fluoride (LiF), both in bulk and lower-density homogeneous thin film form.

DEPTH DOSE MEASUREMENTS WITH LITHIUM FLUORIDE

American Journal of Roentgenology, 1968
Per cent depth doses were measured with LiF in water phantoms exposed to orthovoltage x rays and cobalt 60 radiation. Agreement within ±I per cent was achieved between LiF and ionization chamber measurements of cobalt 60 per cent depth dose. Unsatisfactory results were obtained with LiF measurements of per cent depth dose from orthovoltage x rays.

Picosecond Neodymium:Yttrium Lithium Fluoride Laser Sclerectomy

American Journal of Ophthalmology, 1993
The picosecond neodymium:yttrium lithium fluoride laser, a high-power, short-pulse laser that uses low energy per pulse and has a high repetition rate and a highly coherent energy source of 1,053 nm, was used to perform sclerectomies by an ab externo approach in human cadaver eyes.

Supralinearity of Thermoluminescent Phosphor Lithium Fluoride

Nature, 1970
THE non-linear response to dose reported for many thermoluminescent phosphors1,2 has caused serious concern both for dosimetry and for dating techniques.

INFRARED SPECTRA BY MATRIX ISOLATION OF LITHIUM FLUORIDE, LITHIUM CHLORIDE, AND SODIUM FLUORIDE

The Journal of Physical Chemistry, 1963
The matrix isolation method, which was adapted for infrared spectroscopy of molecular species existing at high temperatures by Linevsky, was employed to examine the spectra of LiF, LiCl, and NaF. Rather complex spectra were found. Most of the features of these spectra must arise from polymeric alkali halide species.

Single-crystal lithium fluoride detectors

Soviet Atomic Energy, 1985
The use of lithium fluoride as detectors for thermoluminescence dosimetry is discussed. The principal characteristics of detectors of diameters 3, 8, and 10 mm are discussed, including: lower limit of detectable dose, repeated use of detectors, dependence of the thermally stimulated luminescence yield on the radiation dose, and loss of accumulated ...

Preparation of thermoluminescent lithium fluoride

Journal of Physics D: Applied Physics, 1970
The preparation of lithium fluoride with thermoluminescence properties suitable for use in radiation dosimetry has been investigated. Variants based on magnesium and titanium additions have been prepared and examined from the viewpoint of activator concentration, role of secondary impurity and purity of the lithium fluoride starting material.

Lithium Fluoride Placement: A New Method

Radiology, 1969
With the acquisition of a lithium fluoride unit for dosimetry, the problem of placing dosimetry disks and rods has become a major one in obtaining accurate and comparable readings throughout the patient's course of therapy. Particularly perplexing was the manner of inserting the rods into the urinary bladder to evaluate the accuracy of rotational or ...
