Diffusing Alpha Emitters Radiation Therapy: Theoretical Modeling

Modeling Internal Radiation Therapy

A new technique is described to model (internal) radiation therapy. It is founded on morphological processing, in particular distance transforms. Its formal basis is presented as well as its implementation via the Fast Exact Euclidean Distance (FEED) transform. Its use for all variations of internal radiation therapy is described. In a benchmark trial, FEED proved to be truly exact as well as f...

A Physical Model of Lyman Alpha Emitters

We present a simple physical model for populating dark matter (DM) halos with Lyman Alpha Emiiters (LAEs) and predict the physical properties of LAEs at z ≈ 3− 7. The central tenet of this model is that the Lyα luminosity is proportional to the star formation rate (SFR) which is directly related to the halo mass accretion rate. The only free parameter in our model is then the starformation effi...

Radium–the Benchmark for Alpha Emitters

States have handled plutonium. Of those workers, only about fifty, all from the nuclear-weapons complex, have been exposed to plutonium at levels above the maximum permissible dose. Because so few people have high-dose exposures, we have little direct information about the risk of plutonium in man. This leads to the ironic situation that the better we protect our workers, the less we know about...

Radiation doses and risks from internal emitters.

This review updates material prepared for the UK Government Committee Examining Radiation Risks from Internal Emitters (CERRIE) and also refers to the new recommendations of the International Commission on Radiological Protection (ICRP) and other recent developments. Two conclusions from CERRIE were that ICRP should clarify and elaborate its advice on the use of its dose quantities, equivalent ...
