Investigation of the bubble detector response to high LET space radiation
The radiation environment aboard spacecraft is a complex mixture of neutrons, photons, protons, heavy ions and other particles. A special type of superheated droplet detectors referred to as space bubble detectors (SBD) have been used to evaluate the equivalent dose due to neutrons in various space …

“Acid-spike” effect in spurs/tracks of the low/high linear energy transfer radiolysis of water : potential implications for radiobiology and nuclear industry
… are formed within spurs or tracks of the low or high linear energy transfer (LET) radiolysis of pure, deaerated water at early times. The in situ radiolytic formation of H3O+ renders the spur and track regions temporarily more acid than the surrounding medium. Although experimental evidence for …

Do heavy ions induce the bystander effect? : study to determine the induction of the bystander effect from Fe ion beam compared to X-rays in human keratinocytes
… non-irradiated cells near a cell traversed by radiation express biological responses such as micronuclei formation and genomic instability. Most published studies of the bystander effect have been conducted using alpha particles, a high LET radiation. A few studies have been done with low LET …

Evaluation of 64Cu-ATSM in cell culture for potential use as a radiotherapy agent
… to traditional low linear energy transfer (LET) external beam radiotherapy (EBRT), instigating interest in finding alternative and more effective means to treat these tumors. 64Cu-diacetyl-bis(N4-methylthiosemicarbazone) (64Cu-ATSM) has shown clinical usefulness in imaging and experimental …

The effect of high dose rate on tissue equivalent proportional counter measurements in mixed neutron-gamma fields
… counters (TEPCs) are commonly used for radiation monitoring in areas where a mixture of neutron and photon radiations may be present, such as those commonly encountered in nuclear power plants. In such radiation fields, the dose rate of each component can vary drastically from extremely …

Monte Carlo simulation of the radiolysis of water by fast neutrons at elevated temperatures up to 350°C
… difficult due to the extreme conditions of high temperature, pressure, and mixed neutron/γ-radiation fields, which are not compatible with normal chemical instrumentation. For these reasons, theoretical models and computer simulations are essential for predicting the detailed radiation …

Radiobiological mechanisms and novel imaging biomarkers in metastatic prostate cancer treated with radium-223
… and α-particle source) and systemic (radium-223) radiation in vitro on a panel of cancer cell lines through various radiobiological endpoints such as cell survival, DNA damage, changes in the cell cycle distribution and the mechanism of cell death. The obtained results indicate that high-LET …
