Use of active personal dosimeters in hospitals: EURADOS survey
The objective was to collect data about the use of APDs
and to identify the basic problems in the use of APDs in hospitals. APDs are most frequently used in
interventional radiology and cardiology departments (54%), in nuclear medicine (29%), and in
radiotherapy (12%). Most types of APDs use silicon diodes as the detector; however, in many cases
their calibration is not given proper attention, as radiation beam qualities in which they are
calibrated differ significantly from those in which they are actually used. The survey revealed
problems related t... (Source: Journal of Radiological Protection)

Radiation characterisation and dosimetric measurements of a femtosecond pulsed laser ablation system
This work describes the radiation characterisation and dosimetric measurements performed on the
low-energy micromachining station of the femtosecond STELA (Santiago TErawatt LAser) at the
University of Santiago de Compostela (Spain). For this aim, ionisation chambers, solid state
detectors, and radiochromic films were used. The results show the emission of pulsed x-ray produced
by laser-accelerated electrons from the ablated material exhibiting both bremsstrahlung and
characteristic radiation. Although this radiation was produced unintentionally, a high superficial
dose rate can be achieved. This radiation can be suc...

A systematic experimental study of parameters influencing 131-iodine in vivo spectroscopic
measurements using age-specific thyroid phantoms
In this study, the influence on the calibration of the
thyroid volume, the counting distance and the positioning variations are studied experimentally in a
systematic way. A NaI and a germanium detector along with a realistic age-specific set of four
thyroid phantoms were used to carry out this study. The thyroid phantom volumes correspond to the
following ages: 5, 10, 15 and adult. It was found that the counting efficiency varies linearly with
the thyroid volumes for both detectors and whatever the phantom –detector distance is. The variation
in counting distance strongly influences the measurement. Whatever the t...
