PURPOSE The purpose of this paper was to observe and compare long-term curative effects and complications of FIGO stage IIB cervical cancer patients (n = 232) treated with high-dose-rate (HDR) californium ((252)Cf) neutron or cobalt ((60)Co) photon intracavitary brachytherapy (ICBT) combined with external-beam radiotherapy (EBRT). MATERIAL AND METHODS The EBRT dose to the small pelvis was 50 ...

The fission fragments and heavy ions tracks in CR-39 detectors registered by Cf-252 radioactive source have been observed by using photo-spectrometric techniques. CR39 detectors were exposed at 5 cm distance from radioactive source for registering nuclear tracks created by nuclear particles emitted from Cf-252 radioactive source. Cr-39 detectors were etched in 6N NaOH solution at 70 C for 400 m...

This study evaluated the 4-year results of 32 patients with T1N0 low-lying rectal adenocarcinoma treated solely with californium-252 (Cf-252) neutron intracavity brachytherapy (ICBT). Patients were solicited into the study from January 2008 to June 2011. All the patients had refused surgery or surgery was contraindicated. The patients were treated with Cf-252 neutron ICBT using a novel 3.5-cm d...

During orbital or interplanetary space flights, astronauts are exposed to cosmic radiations and microgravity. However, most earth-based studies on the potential health risks of space conditions have investigated the effects of these two conditions separately. This study aimed at assessing the combined effect of radiation exposure and microgravity on neuronal morphology and survival in vitro. In...

If gold had been as abundant on earth as iron, it wouldn’t be as famous for its rarity. If a tiny screw in the cosmic kitchen had been turned by just a bit, iron might have been the one that was most rare and desired, but during the creation of the Universe the course was set differently. Clarifying what astrophysical conditions could explain the observed elemental abundances depends on precise...
