Within seconds of the collapse of the World Trade Center in the September 11 attacks, building materials, electronic equipment, and furniture were pulverized and spread over the area of the Financial District of Lower Manhattan.
Radiation damage is the effect of ionizing radiation on physical objects including non-living structural materials. It can be either detrimental or beneficial for materials. It can be either detrimental or beneficial for materials.
A 0.05 Gy dose will increase death due to cancer 10 fold, from the normal 0.5 per 1000 birth rate to a rate of 5 per 1,000. [ citation needed ] An antenatal dose of 1 Gy in the first trimester causes the lifetime risk of fatal cancer sometime in the child's life to increase from c. 25% in non-exposed humans to 100% in the first trimester after ...
NIST's Building and Fire Research Laboratory created a complex computer model to understand the collapse of the towers. [17] Specifically, they wanted to know if the collapse of a core column could cause the progressive collapse of the whole building. They also modeled the dispersion of the jet fuel and damage to the interior of the building ...
Criticality accidents are divided into one of two categories: Process accidents, where controls in place to prevent any criticality are breached;; Reactor accidents, which occur due to operator errors or other unintended events (e.g., during maintenance or fuel loading) in locations intended to achieve or approach criticality, such as nuclear power plants, nuclear reactors, and nuclear ...

It is unknown whether high-LET radiation could cause the same types of tumors as low-LET radiation, but differences should be expected. [9] The ratio of a dose of high-LET radiation to a dose of x-rays or gamma rays that produce the same biological effect are called relative biological effectiveness (RBE) factors. The types of tumors in humans ...
