A horizontal multi-purpose microbeam system with a single electrostatic quadruplet focusing lens has been developed at the Columbia University Radiological Research Accelerator Facility (RARAF). It is coupled with the RARAF 5.5 MV Singleton accelerat

Depleted uranium (DU) is a dense heavy metal used primarily in military applications. Published data from our laboratory have demonstrated that DU exposure in vitro to immortalized human osteoblast cells (HOS) is both neoplastically transforming and

The high photon sensitivity demonstrated by the newly available phosphors, Al 2 O 3 :C and 7 LiF:Mg,Cu,P, makes them attractive for use in personnel and environmental dosimetry. For potential application in mixed neutron-gamma fields, the relative ne

Ionizing radiations have been shown to be able to induce the death of mammalian cells and initiate mutagenic or carcinogenic change. While all three end points are related through chromosomal changes, the latter in particular is of profound concern t

Measurements of the distributions of interatomic separations for 3.7 MeV diatomic deuterons after passing through Mylar foils 6.4, 10.2 and 19.0 µm thick have been made. CR-39 etched track plastic was used to register the particle tracks. After etch

Using the variance-covariance method and a pair of wall-less spherical ionisation chambers, we have measured the dose mean lineal energy, yD, for 15 MeV neutrons in nine site diameters ranging from 4.7 µm down to 19 nm (mean chord lengths from 3.15

The radiation sciences are increasingly interdisciplinary, both from the research and the clinical perspectives. Beyond clinical and research issues, there are very real issues of communication between scientists from different disciplines. It follow
