Under weapons of mass destruction we will basically discus about nuclear, radioactive, biological, chemical weaponries along with anti- personnel land mines and explosive remnants of war. WMD are weapons that can kill and harm a large number of people as well as destroys property. The meaning and the scope of the term has increased and evolved over the time from aerial bombings to now technical weapons i.e. chemical, biological, radiological, and nuclear weapons (CBRN). Several International treaties and conventions have been signed by many countries but not all of them, for governing the use and development of WMD: Non-Proliferation Treaty (NPT), Partial Test Ban Treaty, Nuclear Seabed Arms Control Treaty, Outer Space Treaty, Comprehensive Test Ban Treaty, Biological and Toxin Weapons Convention (BWC), Chemical Weapons Convention (CWC)
On Mars, humans are exposed to radiation. On Earth, however, humans are protected by a magnetic field. The effects of exposure are severe memory loss, brain damage, and cancer. That would be terrible for scientists, because when they have to go exploring for samples scientists would have to be very cautious. Although the gravity on Mars allows humans to jump higher and run faster, scientists have observed what happens to humans in low-gravity environments, including weakened immune systems, extreme fatigue, and muscle and bone loss.
Previously used for nuclear weapons known as “Runit Dome”. This last text links up with my connections because it was held in eniwetok which was once used for nuclear weapons. This links up with my connection as well as text 2 “Runit dome”. because they both involve with eniwetok linking up with nuclear warfare. Although war may be beneficial towards a country, it has detrimental effects on politics and the society.
In the world of diagnostic medicine, there is one technology that is quite different than the other radiology modalities and that technology is nuclear medicine. Nuclear medicine is very unique, because it helps doctors view how your body is functioning. This type of imaging takes small amounts of radioactive tracers and follows their path through your body. X-rays, CAT scans, and for the most part MRI and ultrasonography, can show how something in your body looks, but Nuclear Medicine can show how your body actually functions. These radiopharmaceutical tracers are made up of carrier molecules that are bonded to a radioactive atom.
This method is some of the time called a Halsted radical mastectomy (Hammer et al., 2008). 2. Radiation treatment Radiation treatment is a disease treatment that utilizations high-vitality X-beams or different sorts of radiation to murder malignancy cells and stifle them from developing. There are two sorts of radiation treatment. Outer radiation treatment utilizes a machine outside the body to send radiation toward the malignancy.
Unfortunately, being as elusive and nocturnal as the cheetahs were made it difficult to spot the problem right away, until the problem was already too large (Wildlife). Now, scientists are finding it difficult to help the cheetah. With research being almost impossible to obtain, they have to rely almost completely on guesswork. In addition, they find it difficult to raise support for the Saharan Cheetahs because there aren’t many pictures of them, making it difficult to connect with people (Wildlife). Now the cheetahs face extinction, and without help, this wonderful predator may never hunt again.
By that means, mercury is suggested to be a possible target for space colonization. Whereas, other suggested options are Moon, Mars and Venus. Bruce Murray referred Mercury as a mini Earth in Moon’s clothing. Mercury does not have atmosphere like Moon, it means heat cannot be transferred by convection. Moreover, as it closest to the sun colonists and sensitive things may need serious precautionary measures, from intense solar radiation.
UV-B radiation is also absorbed by the ozone layer of the atmosphere and only about 6% reaches the Earth's surface, but it causes the main undesirable effects - burns and skin tumors, diseases of the eyes, depression of the immune system. Finally, UV-A radiation is slightly attenuated by the atmosphere, but the biological effect produced by it is approximately 1000 times weaker than that of UV-B radiation. Given the significant impact of UV radiation on the biosphere and human health, it is extremely important to carry out its constant monitoring, as well as to study the factors which determine the arrival of UV radiation to the Earth's
One of them is the use of a polyethylene-based material called RXF1, to build spacecrafts and protect them from deep-space radiations. The most harmful radiations are the secondary radiations that, as explained in the previous paragraph, are X-rays and Gamma rays created by the impact of the electrons with the atoms5. It is shown how secondary radiations are formed in Figure 3 Figure 3 (from source 6) RFX1 will not totally stop the radiations, it will only fragment them, making them less harmful for the astronauts since, contrary from the popular belief, materials like polyethylene with the molecular composition of mostly carbon and hydrogen, will protect the human body better from most of the damage, than any heavy element will do6. Polyethylene not only protects 50% better from solar flares, but can also shield from cosmic radiation 15% better than aluminium can. Although polyethylene has higher percentages of protection than aluminium, some computer made simulations were created to compare the risk of cell damage with a polyethylene spaceships vs an aluminium one, showed that there was no significant change between the two
Examples of negative local practices are the usage of poison/explosives and overfishing. Overfishing as the name suggests, is fishing a certain fish to an excess amount, decimating the population. This could put multiple organisms’ populations at risk and populations may possibly go extinct. Another practice that negatively impacts the ocean is the usage of poison and explosives. Obviously, the poison that is used in fishing (mainly cyanide) is harmful for the ocean because it may poison other fish over the years.
