Neutron flux measurement is integral to nuclear physics, with implications across nuclear engineering, medical physics, and material science. This study details neutron flux mapping in the TRIGA reactor in Vienna using the gold foil activation method. Identical gold foils were prepared, subjected to 10-minute irradiation within the reactor core, and subsequently assessed using a 4πβ counter. The neutron flux distribution was theoretically modeled as a Bessel function and cross-referenced against measured activities to yield an experimental thermal neutron flux map. Findings reveal a close alignment between theoretical and experimental data, with a slight flux increase at the core's outermost periphery due to the graphite reflector. This work contributes valuable data on the TRIGA reactor's neutron flux distribution, with broader applicability in the field of reactor experiments and operation.

The peripheral nervous system is an essential component of the microenvironment of the cervix. Nerves regulate the physiological functions of internal organs and participate in the trophic process, tissue development, recovery and regeneration. It is also known that nerve endings release various neurotransmitters. Mechanisms of stimulation of nerve growth during tissue development and regeneration remain unclear. The Role of the nervous microenvironment in tumour processes has not yet been studied, although intensive research is underway to identify biomarkers of nervous tissue; so far, the obtained findings indicate a potentially critical role of the nervous system in carcinogenesis. It is interesting to study what Role other signalling molecules play in the neural regulation of tumours, which are traditionally associated with various functions of the nervous system but at the same time are involved in carcinogenesis. A detailed understanding of the Role of nerves and neural mediators in carcinogenesis can serve as a basis for identifying new biomarkers and developing new preventive, early detection or therapeutic strategies for different types of cancers.
