Neutron dose effect relationships at low doses
Radiation and Environmental Biophysics, 1988Stimulated by recent observations of non-linearity in the dose effect relationship for the transformation of mammalian cells in vitro by fission neutron irradiation and the reverse dose rate effect in this system, the data for mutation induction in the stamen hairs of Tradescantia occidentalis has been re-examined.

THE EFFECTIVE DOSE EQUIVALENT AND EFFECTIVE DOSE FOR HOT PARTICLES ON THE SKIN
Health Physics, 2005Whole body exposure from photon-emitting hot particles is a relatively new problem. Until recently, the U.S. Nuclear Regulatory Commission required the use of deep dose equivalent (DDE) to estimate and report whole body exposures from hot particles. In this study, effective dose equivalent (EDE) and effective dose (ED) were calculated for point sources

Organ Doses and Effective Dose Equivalent
Radiation Protection Dosimetry, 1985For a modified version of the anthropoid MIRD phantom the organ doses and the effective dose equivalent for external neutron irradiation have been calculated in the past by the so called CHORD method. It was anticipated from a few preliminary Monte Carlo Calculations and based upon basic physical considerations that CHORD results may be generally too ...

Effects of caffeine with repeated dosing
European Journal of Clinical Pharmacology, 1991We have recently demonstrated dose-dependency of caffeine metabolism under multiple dosing conditions. Whether there are persistent pharmacodynamic actions of caffeine under such circumstances is the focus of this report. Nine healthy subjects were given, in randomized 5 day blocks, placebo, 4.2 (low) and 12 (high) mg.kg-1.day-1 of caffeine in 6 ...

Effect of dose on phenytoin absorption
Clinical Pharmacology and Therapeutics, 1980To determine the effect of dose on phenytoin bioavailability, a single intravenous 15-mg/kg dose, single oral doses of 400, 800, and 1,600 mg, and 1,600 mg in divided doses (400 mg every 3 hr) were given to six healthy male subjects. Values of Vmax (maximum elimination rate) and Km (serum concentration at which rate of elimination is one half the ...

Effects of high-dose cytarabine
Clinical Pharmacology and Therapeutics, 1982Plasma, urine, cerebrospinal fluid, and tear concentrations of cytarabine (ara-C) were measured in 15 patients receiving 3 gm/m2 IV ara-C given as a 1 hr infusion every 12 hr for 6 days. The two assay methods used for measuring ara-C concentrations (high-pressure liquid chromatography and radioimmunoassay) gave much the same results.

Dose normalization and pre-dose effect
Nuclear Tracks and Radiation Measurements (1982), 1985Abstract Dose normalization of the TL signal from quartz and feldspar used for dating is often complicated by the pre-dose effect resulting from the samples having received different doses prior to application of the monitor dose. Assuming that the pre-dose effect increases linearly with dose the normalized build-up curves can be expressed by the ...

Effects of Low Doses of Radiation
Health Physics, 1996This is a brief review of what is known from experimental studies about the effects of low doses of radiation, and approaches that might improve risk estimates are discussed. The dose-response relationships for cancer induction by radiation vary markedly between tissues.
