In many countries the education and training of medical physicists has changed over the last few decades from being rather ad hoc to becoming structured with residency programs becoming quite common. These are often followed by formal certi...
Hidden stressors in the clonogenic assay used in radiobiology experiments [0.03%]
放射生物学实验中克隆形成试验的隐匿应激因素
M D E Potter,N Suchowerska,S Rizvi et al.
M D E Potter et al.
While clonogenic assays are extensively used in radiobiology, there is no widely accepted procedure for choosing the composition of the cell culture media. Cell line suppliers recommend a specific culture medium for each cell line, however ...
A hybrid radiation detector for simultaneous spatial and temporal dosimetry [0.03%]
一种用于同时进行空间和时间剂量测量的混合辐射探测器
C Poole,J V Trapp,J Kenny et al.
C Poole et al.
In this feasibility study an organic plastic scintillator is calibrated against ionisation chamber measurements and then embedded in a polymer gel dosimeter to obtain a quasi-4D radiation detector. This hybrid dosimeter was irradiated with ...

David L Thiele et al.
Diagnostic reference levels assist in the optimisation of radiation exposure parameters within a medical imaging facility. As no Australian DRLs currently exist, radiation doses from mammography in BreastScreen Queensland are analysed. Prog...
A fast numerical method for calculating the 3D proton dose profile in a single-ring wobbling spreading system [0.03%]

Based on the determination of protons fluence at the phantom's surface, a 3D dose distribution is calculated inside a water phantom using a fast method. The dose contribution of secondary particles, originating from inelastic nuclear intera...
Monte Carlo study of the energy response and depth dose water equivalence of the MOSkin radiation dosimeter at clinical kilovoltage photon energies [0.03%]
一种基于MOS皮肤辐射剂量计的临床千伏光子能量下的能量响应和深度剂量当量水的研究的蒙特卡罗研究
