Abstract

One of the missions of the Bulgarian Army is the formation of maintenance modules that can take part in a series of military activities, including the eradication of the consequences of natural disasters, chemical and radiological accidents and ecological catastrophes. One task of the module formations in chemical and radioactive incidents is decontamination of equipment, materials and people. Pollution with toxic substances can occur in the area of military operations, tank spills, and terrorist attacks in peacetime. The Hazard Index ranks TIMs according to the chemical's production, transport, storage, toxicity, and vapor pressure. Mineral acids considered „high hazards" are also having a high level of toxicity and vaporize easily. This paper provides some chemical tasks about acids decontamination on non-porous materials. We have investigated the decontamination of hydrochloric and nitric acid in the non-porous surfaces through calculations and their decontamination on wood and concrete surfaces

Abstract

In the 1999 bombing of the Federal Republic of Yugoslavia, NATO forces used ammunition containing depleted uranium. The cleaning of depleted uranium that followed was performed in southern Serbia by the Vinča Institute of Nuclear Sciences between 2002 and 2007 at the locations of Pljačkovica, Borovac, Bratoselce, and Reljan. This paper presents detailed results of radioactivity monitoring four years after cleaning (2011), which included the determination of gamma emitters in soil, water, and plant samples, as well as gross alpha and beta activities in water samples. The gamma spectrometry results showed the presence of natural radionuclides 226Ra, 232Th, 40K, 235U, 238U, and the produced radionuclide 137Cs (from the Chernobyl accident). In order to evaluate the radiological hazard from soil, the radium equivalent activity, the gamma dose rate, the external hazard index, and the annual effective dose were calculated. Considering that a significant number of people inhabit the studied locations, the periodical monitoring of radionuclide content is vital.

Abstract

Background: Since they’re rare, the intraventricular neoplasms “central neurocytoma” best management got diverse, and mystifying.

Aim of the work: to assess outcome for patients with central neurocytoma and value of specific factors like tumor size, surgical resection extent, atypia, and concomitant other modality of treatments by radiotherapy in their survival.

Patients & methods: 14 patients (8 males, 6 females) were managed surgically between 2012 and 2016. They were assessed clinically, radiologically and their outcome in relation to selected factors.

Results: Median age at diagnosis was 28.3 years in average (range 16–58). Median follow-up was 32.2 months.we lost 2 cases to follow-up in post-operative period. Six patients had recurrent of neurocytoma tumours.Five patients (35.7 %) obtained gross total resections (GTR) while 9 patients (64.2 %) had subtotal resections (STR). Two STR patients (14.2 %) received dose of radiation post operatively that significantly enhanced overall PFS (p =0.047). our series data propose that radiation therapy following (STR) usually increase (PFS). Two patients proved to have atypical neurocytoma by pathological reports died at 2.3 and 10.2 months after the microsurgical procedures. MIB-1 tagging index higher than 4 % is an indicator for poor outcome. We used Kaplan–Meier beside Cox proportional hazards methods in determining the Progression-free survival (PFS) in our study.

Conclusion: the extent of surgical resection may improve the neurological condition but not the survival, Atypia was the most important factor determine the recurrence & survival while radiotherapy improve the survival quietly.
