Microdosimetry in Radioimmunotherapy

Radiation Protection Dosimetry, 1990
Abstract Antibodies are rapidly being developed which target radionuclides to tumour tissue. The MIRD formulation to calculate absorbed dose from internal emitters has limitations in radiation targeted therapy because of the heterogeneity of antibody distribution through the tumour.

Microdosimetry of Internal Sources

Radiation Research, 1977
ROESCH, W. C. Microdosimetry of Internal Sources. Radiat. Res. 70, 494-510 (1977). Microdosimetry has been limited to irradiations characterized by uniform probabilities of charged-particle production. New methods are presented here for dealing with particles emitted by radionuclides embedded in the irradiated medium; these particles seldom emerge ...

Microdosimetry of Plutonium in Lungs

Health Physics, 1983
Chord length distributions for alveolar cells and cell nuclei were determined by superimposing computer-generated alpha-particle tracks on magnified images of randomly selected rat lung sections using the Quantitative Television Microscope. Specific energy distributions were then calculated by applying image analysis techniques.

The role of microdosimetry in radiobiology

Radiation and Environmental Biophysics, 1979
Microdosimetry is a branch of radiological physics that provides quantitative characterization of the non-uniformity of energy deposition in uniformly irradiated matter. Consideration based on microdosimetry indicate that the action of ionizing radiation on the cells of higher organisms depends on the square of the specific energy absorbed in ...

Microdosimetry of Negative Pions at LAMPF

Radiology, 1975
Lineal energy distributions and linear energy transfer (LET) spectra are being measured at the biomedical facility of the Los Alamos Scientific Laboratory for a negative pion beam having an initial momentum of 168 MeV/c. The results show that the fraction of the dose for lineal energies greater than 50 keV/mum is approximately 2% in the plateau and ...

Microelectronics and microdosimetry

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1987
The dimensions of electronic components have been steadily decreasing until radiation-sensitive sites are now at the micrometer level. Reduced size generally has corresponded to improved performance and increased computing speed; however, it also resulted in an unanticipated increase in vulnerability to radiation.

Microdosimetry of Alpha-irradiated Lung

Health Physics, 1984
Measurements have been made on the fractions of tissue affected and distributions of energy deposited when rat and human lung are irradiated by alpha particles. Thin sections of alveolar tissue were examined in an image analyser and an imaginary 239PuO2 particle was placed in an alveolar sac.

Microdosimetry of proton and carbon ions

Medical Physics, 2014
Purpose:To investigate microdosimetry properties of 160 MeV/u protons and 290 MeV/u12C ion beams in small volumes of diameters 10–100 nm.Methods:Energy distributions of primary particles and nuclear fragments in the beams were calculated from simulations with the general purpose code SHIELD‐HIT, while energy depositions by monoenergetic ions in ...

Dosimetry and Microdosimetry of Targeted Radiotherapy

Current Pharmaceutical Design, 2000
Dosimetry in targeted radiotherapy (TR) uses different calculation methods, whose degree of refinement is closely conditioned by the particular objective sought. It is more generally performed to establish a correlation between the quantity of radiation delivered to a target and the biological damage observed or that can be reliably predicted.
