Abstract
Polymeric porous scaffolds are a key component in several
bioengineering and biomedical applications. In a recent development,
we have introduced a novel approach for the designing of macroporous
matrices by combining $\gamma$-radiation with cryogelation technology.
This new prototype has been optimized and compared with the classical
cryogelation technology. The acrylic...

Introduction; For tracer experiments in life science field, many types of compound are labeled with beta-emitters. The beta-emitters are generally measured using an liquid scintillation counter (LSC) because of their low energies. An LSC is a superior machine with high counting efficiency; however, there are mainly 2 demerits. Organic liquid wastes are generated after measurement because the...

Polychlorinated biphenyls (PCBs) belong among the most persistent and bioaccumulative substances. Long-term production of PCBs in the 20th century has resulted in excessive concentrations of this organic pollutant in the environment with about 200,000 inhabitants in the eastern Slovakia. There were evaluated different techniques of removing PCBs in sediments, but...

IRRADIATION FACILITIES
Poster
Radiation processing technology started in Tunisia by the installation of a pilot plant gamma irradiator in 1999 in National Centre for Nuclear Science and Technology (CNSTN) situated at about 20 km in north of the capital Tunis. This facility was established with the support of the International Atomic Energy Agency (IAEA) in the frame of the technical co-operation assistance program and the...

In any irradiation facility, upgrading of $^{60}$Co activity is
one of the most important maintenance operations, which should be done
periodically to maintain the dose rate in the irradiation process
given the decay of $^{60}$Co. In general there are two kinds
of irradiator with either wet storage or dry storage
of $^{60}$Co in the facility.
For wet storage facilities, the $^{60}$Co...

FUNDAMENTAL AND APPLIED RADIATION CHEMISTRY RESEARCH
Poster
There are 2 general types of radiation used for sterilization, ionizing radiation and non-ionizing radiation. Ionizing radiation is the use of short wavelength, high-intensity radiation to destroy microorganisms. This radiation can come in the form of gamma or X-rays that react with DNA resulting in a damaged cell. Non-ionizing radiation uses longer wavelength and lower energy. As a result,...
