Non-Ionizing Radiation around Tanning Beds

Natural Science and Discovery, 2015
Objective: Use of artificial tanning devices that emit UV radiation, such as tanning lamps and tanning beds, has become increasingly popular in the world. A tanning bed is a device emitting ultraviolet radiation used to produce a cosmetic tan. A number of studies have been conducted evaluating the risk of cutaneous malignant melanoma after exposure to

Energy dependence of the GAFCHROMIC LD‐V1 in the diagnostic radiographic modalities

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract The GAFCHROMIC LD‐V1 radiochromic film is widely used in dosimetry because it can provide high‐resolution two‐dimensional dose distributions without processing. This study aimed to evaluate the response characteristics at different effective energies, from the low‐energy range of mammography to the high‐energy range of computed tomography. Net

How Very Massive Metal Free Stars Start Cosmological Reionization [PDF]

, 2007
(Abridged) Using ab initio cosmological Eulerian adaptive mesh refinement radiation hydrodynamical calculations, we discuss how very massive stars start the process of cosmological reionization. The models include non-equilibrium primordial gas chemistry

Long‐term stability analysis of beam shape in a robotic radiosurgery system

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose This study aimed to investigate the long‐term stability of CyberKnife beam profile parameters and assess their compliance with existing quality assurance (QA) guidelines. We evaluated beam profiles in both standard and diagonal planes over 3.5 years post‐installation to detect potential issues and ensure consistent beam quality.

A review of advances in pixel detectors for experiments with high rate and radiation

, 2018
The Large Hadron Collider (LHC) experiments ATLAS and CMS have established hybrid pixel detectors as the instrument of choice for particle tracking and vertexing in high rate and radiation environments, as they operate close to the LHC interaction points.
