NASA Space Radiation Laboratory
The NASA Space Radiation Laboratory (NSRL, previously called Booster Applications Facility), is a heavy ion beamline research facility; part of the Collider-Accelerator Department of Brookhaven National Laboratory, located in Upton, New York on Long Island. Its primary mission is to use ion beams (H+to Bi83+) to simulate the cosmic ray radiation fields that are more prominent beyond Earth's atmosphere. Overview Jointly managed by the U.S. Department of Energy's Office of Science and NASA's Johnson Space Center, the facility employs beams of heavy ions that simulate the cosmic rays found in space. NSRL also features its own beam line dedicated to radiobiology research, as well as specimen-preparation areas. Although Brookhaven Lab researchers and their colleagues used heavy ion beams for radiobiology research at another Brookhaven accelerator from 1995, the NSRL became operational during summer 2003, and over 75 experimenters from some 20 institutions from the U.S. and abroad have ...

Upton, New York
Upton is a hamlet and census-designated place (CDP) located on Eastern Long Island in the town of Brookhaven in Suffolk County, New York, United States. It is the home of the Brookhaven National Laboratory and a National Weather Service (NWS) Weather Forecast Office (WFO) on the grounds of the national lab. This NWS WFO is code "OKX", and serves the New York metropolitan area. The town is so named because it was the site of the U.S. Army's Camp Upton, which was active from 1917 until 1920, and again from 1940 until 1946. During World War II, the camp was rebuilt primarily as an induction center for draftees. The Army was later to use the site as a convalescent and rehabilitation hospital for returning wounded. The 32 megawatt (MW) Long Island Solar Farm (LISF), located in Upton, is the largest photovoltaic array in the eastern United States. The LISF is made up of 164,312 solar panels which provide enough electricity for roughly 4,500 households. The project will cause t ...

Cosmic Ray
Cosmic rays or astroparticles are high-energy particles or clusters of particles (primarily represented by protons or atomic nuclei) that move through space at nearly the speed of light. They originate from the Sun, from outside of the Solar System in our own galaxy, and from distant galaxies. Upon impact with Earth's atmosphere, cosmic rays produce showers of secondary particles, some of which reach the surface, although the bulk are deflected off into space by the magnetosphere or the heliosphere. Cosmic rays were discovered by Victor Hess in 1912 in balloon experiments, for which he was awarded the 1936 Nobel Prize in Physics. Direct measurement of cosmic rays, especially at lower energies, has been possible since the launch of the first satellites in the late 1950s. Particle detectors similar to those used in nuclear and high-energy physics are used on satellites and space probes for research into cosmic rays. Data from the Fermi Space Telescope (2013) have ...

Brookhaven, New York
Brookhaven is a large Suburb, suburban town in Suffolk County, New York, Suffolk County, Long Island, New York (state), New York. With a population of 488,497 as of 2022, it is the second most populous town in New York (after Hempstead, New York, Hempstead, in the adjacent Nassau County, New York, Nassau County) and the third most populous community in the state. The first settlement in what is now Brookhaven was known as Setauket, New York, Setauket. Founded as a group of agricultural hamlets in the mid-17th century, Brookhaven first expanded as a major center of shipbuilding in the 19th century. Its proximity to New York City facilitated the establishment of resort communities, followed by a post-war population boom. In the 2020 census record, Brookhaven contained 485,773 people. The township is home to two renowned Research institute, research centers, Stony Brook University and Brookhaven National Laboratory. Combined these two research centers are approximately 50% of ...

Particle Physics Facilities
In the Outline of physical science, physical sciences, a particle (or corpuscle in older texts) is a small wikt:local, localized physical body, object which can be described by several physical property, physical or chemical property, chemical properties, such as volume, density, or mass. They vary greatly in size or quantity, from subatomic particles like the electron, to microscopic scale, microscopic particles like atoms and molecules, to macroscopic scale, macroscopic particles like powder (substance), powders and other granular materials. Particles can also be used to create scientific models of even larger objects depending on their density, such as humans moving in a crowd or celestial bodies in motion (physics), motion. The term ''particle'' is rather general in meaning, and is refined as needed by various scientific fields. Anything that is composed of particles may be referred to as being particulate. However, the noun ''particulates, particulate'' is most frequently u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Particle Therapy
Particle therapy is a form of external beam radiotherapy using beams of energetic neutrons, protons, or other heavier positive ions for cancer treatment. The most common type of particle therapy as of August 2021 is proton therapy. In contrast to X-rays (photon beams) used in older radiotherapy, particle beams exhibit a Bragg peak in energy loss through the body, delivering their maximum radiation dose at or near the tumor and minimizing damage to surrounding normal tissues. Particle therapy is also referred to more technically as hadron therapy, excluding photon and electron therapy. Neutron capture therapy, which depends on a secondary nuclear reaction, is also not considered here. Muon therapy, a rare type of particle therapy not within the categories above, has also been studied theoretically; however, muons are still most commonly used for imaging, rather than therapy. Method Particle therapy works by aiming energetic ionizing particles at the target tumor. These par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synchrotron
A synchrotron is a particular type of cyclic particle accelerator, descended from the cyclotron, in which the accelerating particle beam travels around a fixed closed-loop path. The strength of the magnetic field which bends the particle beam into its closed path increases with time during the accelerating process, being ''synchronized'' to the increasing kinetic energy of the particles. The synchrotron is one of the first accelerator concepts to enable the construction of large-scale facilities, since bending, beam focusing and acceleration can be separated into different components. The most powerful modern particle accelerators use versions of the synchrotron design. The largest synchrotron-type accelerator, also the largest particle accelerator in the world, is the Large Hadron Collider (LHC) near Geneva, Switzerland, completed in 2008 by the European Organization for Nuclear Research (CERN). It can accelerate beams of protons to an energy of 7 electron volt, teraelectro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armed Forces Radiobiology Research Institute
The Armed Forces Radiobiology Research Institute (AFRRI) is an American triservice research laboratory in Bethesda, Maryland chartered by Congress in 1960 and formally established in 1961. It conducts research in the field of radiobiology and related matters which are essential to the operational and medical support of the U.S. Department of Defense (DoD) and the U.S. military services. AFRRI provides services and performs cooperative research with other federal and civilian agencies and institutions. History Department of Defense (DoD) interest in the health effects of exposure to radiological agents (radiobiology), born in the wake of the Manhattan Project, motivated a 1958 Bureau of Medicine and Surgery proposal that a bionuclear research facility be established to study such issues. On June 8, 1960, Public Law 86-500 authorized the construction of such a facility, including a laboratory and vivarium under the Defense Atomic Support Agency (DASA, now the Defense Threat Reduc ...

Health Threat From Cosmic Rays
Astronauts are exposed to approximately 72 millisieverts (mSv) while on six-month-duration missions to the International Space Station (ISS). Longer 3-year missions to Mars, however, have the potential to expose astronauts to radiation in excess of 1000 mSv. Without the protection provided by Earth's magnetic field, the rate of exposure is dramatically increased. The risk of cancer caused by ionizing radiation is well documented at radiation doses beginning at 100 mSv and above. Related radiological effect studies have shown that survivors of the atomic bomb explosions in Hiroshima and Nagasaki, nuclear reactor workers and patients who have undergone therapeutic radiation treatments have received low-linear energy transfer (LET) radiation (x-rays and gamma rays) doses in the same 50-2,000 mSv range. Composition of space radiation While in space, astronauts are exposed to radiation which is mostly composed of high-energy protons, helium nuclei (alpha particles), and hi ...
