We previously reported that methoxyamine (an inhibitor of base excision repair) potentiates iododeoxyuridine (IUdR)-induced radiosensitization in human tumor cells. In this study, we investigated the potential mechanisms of this enhanced cell death. Human colorectal carcinoma RKO cells were exposed to IUdR (3 micromol/L) and/or methoxyamine (3 mmol/L) for 48 hours before ionizing radiation (5 G...

Radiofrequency radiation (RFR), e.g. electromagnetic waves emitted by our cell phones and Wi-Fi, are referred to as non-ionizing. This means that in contrast to the ionizing radiation, which does induce ionization of water and biologically important macromolecules, RFR does not have a capacity for such effects. Unlike, for example X-rays, the energy of RFR is not enough to break electrons off t...

Nuclear medicine uses ionizing radiation for both in vivo diagnosis and therapy. Ionizing radiation comes from a variety of sources, including x-rays, beam therapy, brachytherapy, and various injected radionuclides. Although PET and SPECT remain clinical mainstays, optical readouts of ionizing radiation offer numerous benefits and complement these standard techniques. Furthermore, for ionizing ...

Radiation safety is one of the most important issues for free electron laser [FEL] facilities and the users. Many FEL facilities are under operation worldwide, and their number is growing. The wave length of FEL ranges from a few millimeters to about 0.5 nm, and the electron energy is from a few MeV to about 20 GeV. Furthermore, various kinds of electron accelerator types are constructed for FE...

Present review article describes use of radiation and radionuclides on cancer cell therapeutics. It also sketches out cumulative effects exposure received by the patients during diagnostics. Though, in therapeutics a selected permissible dose is provided several cycles to ablate neoplastic cells improve condition patient, but harms surrounding imparts negative biology cells. Ionizing (IR) promo...

The study considers the impact of environmental contamination by electromagnetic radiation electron beam generator and high-energy radioactive source on memory components. Electron can be used for injecting particle energy into plasma fusion system based a Marx generator, while as simulator ionizing that caused neutron-induced activation surrounding structures or released from deuterium-tritium...

The widespread use of mobile phones and other wireless communication devices raises concerns about radiation’s impact on humans. A new algorithm for making decisions the assessment biological non-ionizing radiation is presented in this paper. was developed according to ICNIRP (the International Commission Non-Ionizing Radiation Protection) guidelines using fuzzy logic. Appropriate membership fu...

Evidence of health benefits and longer average life-span following low-dose irradiation should replace fear, “all radiation is harmful,” and “the perception of harm” as the basis for action in the 21 century. Hormesis is the excitation, or stimulation, by small doses of any agent in any system. Large doses inhibit. “Low dose” is defined as any dose between ambient levels of radiation and the th...
