Binding energies of nuclei are calculated in the mass region 900 ≤ A < 1000. The calculations are performed using the modified Rost interaction which suggests that a new island of stability exists at the Z = 282 shell. Enhanced stability occurs in the doubly closed 926 282X664 system. © 2017 Physics Essays Publication.

The TMI-2 and Fukushima Daiichi accidents appear to be dissimilar because they involve different reactor types. However, the health physics related lessons learned from TMI-2 are applicable, and can enhance the Fukushima Daiichi recovery effort. © 2011 Elsevier Ltd.

The ALARA Principle ensures that the total effective dose equivalent is minimized subject to economic and social factors. Effective ALARA programs must include the participation of all facility workgroups, management support, teamwork, and strong leadership. The development and sustainability of effective ALARA programs require the establishment and monitoring of goals, rewarding the successful achievement of those goals, and incorporating lessons learned from tasks that fail to meet their goals. © 2010 Health Physics Society.

The Standard Model of Particle Physics is reviewed with an emphasis on its relationship to the physics supporting the health physics profession. Concepts important to health physics are emphasized and specific applications are presented. The capability of the Standard Model to provide health physics relevant information is illustrated with application of conservation laws to neutron and muon decay and in the calculation of the neutron mean lifetime. © 2010 Health Physics Society.

Recently discovered tetraquark structures are investigated using a first-order mass formula. This mass relationship is based on weakly bound cc plus dū meson clusters and provides a reasonable prediction of the measured Z(4430)- tetraquark mass. © 2016 Physics Essays Publication.

The feasibility of using radiation-generating devices located within a tumor mass for radiotherapy applications is investigated. This paper presumes the existence of these devices and develops their requisite characteristics and possible arrangement configurations to permit the selective irradiation of tumors. Calculations are provided for a prototypical proton-generating device. © 2010 Health Physics Society.

Binding energies of nuclei are calculated in the mass region 700≥A>800. The calculations are performed using the interaction of Rost, which suggests that a new island of stability may exist near the N=504 shell for a small range of A values associated with the Z=226 shell. © 2014 Physics Essays Publication.

The angular dependence of the absorbed dose from internal radiation-generating devices located within a tumor mass is investigated. Given the systematics of proton and heavy-ion differential scattering cross sections, candidate internal radiation-generating devices will have a relatively constant absorbed dose output beyond a critical angle. Inside this angle, the absorbed dose output is suppressed because elastic and inelastic differential cross sections are peaked in the beam direction. This peaking increases in severity as the particle energy increases and suggests internal radiation-generating devices must have a limited rotation capability to compensate for the depression in the absorbed dose for angles near the beam direction.

Binding energies of nuclei are calculated in the mass region 570 ≤ A ≤ 620. The calculations are performed with the use of the interaction of Rost, which suggests that a new island of stability may exist near the N =406 shell for a small range of A values associated with the Z= 204 shell. © 2012 Physics Essays Publication.
