For the first time, a complete computer simulation of physical and chemical reactions at the molecular level has been used to calculate the yield of a chemical species resulting from irradiation of a biological molecule in aqueous solution. Specifica

The conceptual framework is described for a new type of neutron spectrometer, based on the recently demonstrated principle of optical detection of charged particle tracks in a gas. Whereas the elastic scattering of a neutron gives rise to the single

Detailed-history Monte Carlo computer codes were used to simulate the formation, diffusion, and chemical reaction of free radical species within deoxygenerated solutions of glycylglycine irradiated 250 kVp X rays and by 60Co ? rays. In one reaction,

The Monte Carlo method may be used to simulate chemical reactions occurring in the track of a charged particle. We compare these simulations with predictions of solutions to the diffusion equation. Conditions are delineated when the latter may be use

A fundamentally new technique for the measurement of the number of subexcitation electrons produced by the passage of ionizing radiation (electromagnetic and high energy charged particles) through a gas has been developed by us during the past few ye

We review the state of knowledge about inelastic interactions of swift charged particles with condensed matter. Emphasis is placed on the properties of the dielectric response function and its representation for biologically interesting materials. Pr

The chemotoxicity and radiotoxicity of trans-dichlorodiammineplatinum (II) labeled with 195mPt (trans-195mPt) are investigated to ascertain the potential of radioplatinum coordination complexes as antineoplastic agents. Platinum-195m, with a half-lif

The spatial distributions of ionizations and other inelastic events in charged-particle tracks are important quantities that influence the final outcome of radiation interaction. Calculations of such distributions are presented for the tracks of elec

Detailed-history Monte Carlo computer codes were used to simulate the formation, diffusion, and chemical reaction of free-radical species within deoxygenated aqueous solutions of glycylglycine irradiated by 250-kVp X rays and by 60Co gamma rays. In o

We are developing a new optical ionization detector for imaging the track of a charged neutron-recoil particle in a gas. Electrons produced in the path of the recoil particle are excited by an external, high-voltage, rf, electric field of short durat
