At the molecular and cellular level, cell killing has been attributed to deposition of energy from the radiation in the DNA within the nucleus, with production of DNA double-strand breaks playing a ...

Figure 2 DNA and membranes have been reported to be targets for triggering apoptosis, with the secondary messenger ceramide potentially playing an important part ...

Prolonged exposure to low-dose ionising radiation is associated with a higher risk of death from cancer than previously thought, suggests research tracking the deaths of workers in the nuclear ...

Singer Linda Nolan, part of the famed Irish family group The Nolans, died on Jan. 15, 2025, at the age of 65. Nolan, ...

The cell can repair certain levels of cell damage. At low doses, such as that received every day from background radiation, cellular damage is rapidly repaired. At higher levels, cell death results.

We have all been told to avoid direct sunlight between 12 noon and 3 p.m., seek out shade and put on sunscreen and a hat.

The tour ends with gamma rays, the potentially deadly radiation discussed in the program Death Star. Flash is a plug-in that allows for increased interactivity. If you can see the animated boxes ...

Radiotherapy (RT) includes internal radiotherapy (IRT) and external-beam radiotherapy (EBRT), which use radiation beams such as X-ray, β-ray, or α-ray to directly kill cancer cells and reprogram tumor ...
