Exit dose studies in megavoltage photon therapy.

A coin-shaped ionisation chamber, orientated with its thin window facing away from the radiation source, was used to investigate the dose perturbations caused by the absence of back-scattering material near the exit surface of solid phantoms. Cobalt 60 and 4, 8 and 16 MV X-ray beams were used in the study. With no scattering material beyond the chamber window the ionisation was found to be as much as 17% less than the full scatter value. This was attributed to the absence of both back-scattered electrons and back-scattered photons. Full electron back-scattering could be restored by placing between 1.0 and 2.7 mm of unit density material beyond the chamber, depending on the primary beam energy. Under these circumstances the reduction in dose, now due to the absence of back-scattered photons only, was found to be small.

Pharmacokinetics of resorcinol in the rat.

Pharmacokinetic data on resorcinol were obtained from studies in the rat. The drug, administered subcutaneously in an aqueous solution, rapidly cleared plasma vir urine and did not accumulate in tissues. In the urine, the major metabolite of resorcinol was the glucuronide. Repeated dosing for 30 days with maximum tolerated daily doses of 100 mg/kg did not alter pharmacokinetic parameters, nor did it cause overt toxic signs or adverse reactions. The animals' body weight, blood values, levels of serum T3 and T4' and the gross and microscopic appearance of the thyroid gland and spinal cord remained within normal limits throughout the study.

Charging for services: efficiently, effectively, and easily.

In summary, fiscal awareness and involvement are critical in maintaining one's position as an ET nurse and in supporting both quality care and institutional survival. The authors challenge all ET nurses to work toward the establishment of equitable and reimbursable charging systems, and to share the knowledge gained in the process.
