The paper presents an innovative approach towards development of real time dosimetry using a chemical dosimeter for measurement of absorbed radiation dose in the range between 1 and 400 Gy. Saturated chloroform solution in water, a well known chemical dosimeter, is used to demonstrate the concept of online measurement of radiation dose. The measurement approach involves online monitoring of inc...

The gross and histologic patterns of abdominal adhesions formed by the use of chromic catgut and polypropylene suture materials were evaluated in dogs. Gross and histologic examinations did not reveal significant difference (p>0.05) in the degree of adhesions observed at enteropexy sites in both suture materials. The use of polypropylene with superior suture qualities should be considered inste...

While scintillation dosimetry has been around for decades, the need for a dosimeter tailored to the reality of modern radiation therapy-in particular a real-time, water-equivalent, energy-independent dosimeter with high spatial resolution-has generated renewed interest in scintillators over the last 10 years. With the advent of at least one commercial plastic scintillation dosimeter and the eve...

Ž . Acid-insoluble ash AIA was evaluated as an inert marker material for digestibility studies in Ž . tilapia. No significant differences were found in apparent digestibility coefficients ADC for nitrogen, dry matter or gross energy determined in a practical diet using naturally occurring AIA, Ž . or AIA supplemented with Celitee 0.5%, 1.0% of the diet , compared with values obtained using Ž . ...

Eighty-seven feet have been reviewed after arthrodesis of the first metatarsophalangeal joint stabilised by chromic catgut. Radiological union was present in 90% of patients at the mean review time of six years. Twenty-four patients had significant metatarsalgia before operation and only two failed to improve afterwards. Excellent or good subjective results were reported in 94% of patients at r...

Lancet of that date of some cases of warts on the genitals treated by Mr John Marshall, at University College Hospital, with chromic acid. In one severe case, after having tried all manner of caustics with only temporary benefit, Mr Marshall found the application of chromic acid, gr. 100 to ?j. of water, quite successful, and much less painful than any other escharotic he had tried. In the Lanc...

Magnetic resonance imaging (MRI) is being rapidly integrated for cancer treatments-such systems are referred to as MRI-guided radiation therapy (MRIgRT). As the magnet of an MRI scanner is always on, the presence of a strong static magnetic field from the MRI scanner during radiotherapy delivery presents new challenges. One of the challenges is that a personal radiation dosimeter used to estima...

A radiochromic silicone based dosimeter has been fabricated that allows for threedimensional (3D) dose verification. This paper characterizes the silicone dosimeter and verifies previous results found by other research groups. Using a recipe found to be dose rate independent, we identify the spectra of the dosimeter irradiated to different doses and verify that the response from different dose ...

The Damage Dosimeter has been designed to fill a void in commercially available data recorders. The United States Air Force often has the need to measure structural strains and temperatures on in-service aircraft in order to diagnose difficult-to-analyze structural conditions, such as high cycle fatigue. To perform these functions a rugged, small, and lightweight data acquisition unit called th...
