Ionizing Radiation

Answer: Radiation has a profound effect on matter. Particularly in forms where it has high energy. There are basically two kinds of radiation, and they are electromagnetic energy and particulate radiation. Low energy electromagnetic radiation isn't generally hazardous, as long as the field strengths are low. You wouldn't want to stand in front of a radar antenna when it's radiating, but we are swept by low power electromagnet energy all the time. Those so-called radio waves are everywhere. Light...

Cancer and Radiation

insufficient physical exercise. However, not all known causes of cancer such as ionizing radiation are covered to this extent. How big of a role does ionizing radiation play in cancer deaths? Is it even worth noticing? First, in order to understand why ionizing radiation leads to cancer, an important distinction must be made between ionizing and nonionizing radiation. “Radiation is ionizing if the energy of the radiation suffices to remove an electron from an atom to create an ion. Conversely, if the...

The Effect of Different Levels of Radiation in Growth of Plants.

ABSTRACT The effect of different levels of radiation was determined using four set-ups-10kR, 30kR, 50 kR, and the control (no radiation). The four set-ups were observed for nine weeks and growth (in cm), germination, and survival rate was measured. Results showed that at the right level of radiation level (10 kR), radiation have a positive effect on the plant growth and has the same germination and survival rate from the control set up. The 30 kR set up and 50 kR set up are relatively smaller...

Effect of Radiation to Corn (Zea mays L.)

ABSTRACT Mutation was induced via a physical agent, radiation. 4 levels of radiation—0 kr (control), 10 kr, 30 kr, and 50 kr—were used in seeds to determine the radiation effects on the growth of Zea mays. Using two duplicate set-ups, each, planted with 18 seeds per radiation, the differences in height were observed from January 29 to March 17 in a 1 to 2-day interval (Mondays-Wednesdays-Fridays). Results show that as radiation increases, the potential of plants to grow decreases—0 kr seeds reached...

Negative Effects of Nuclear Radiation

NEGATIVE PHYSICAL EFFECTS OF NUCLEAR RADIATION Page 1 Abstract Nuclear radiation has been a major problem since 1941 when the Second World War began. A major contribution to World War Two is the nuclear bomb, also known as the Atom bomb. Once the two bombs were dropped, the usually terminal Leukemia was derived throughout Japan. There are three types of radiation, Alpha, Beta, and Gamma radiation. In my study of radiation I discovered that radiation can damage many cells in your body as...

dangerous. They emit a type of radiation called radio frequency (RF) that has been shown to damage genetic material in blood cells, which can cause cancer. Radio frequency energy is a form of electromagnetic radiation. Electromagnetic radiation are categorized into two type: ionizing and non-ionizing. Ionizing radiation are found in x-rays, cosmic rays, and radon. Non-ionizing radiations are found in radio frequency and extremely low-frequency or power frequency. Ionizing radiation increase the risk of cancer...

food irradiation

Food irradiation: A food safety technology designed to eliminate disease-causing germs from foods. Treating food with ionizing radiation can kill bacteria and parasites that would otherwise cause foodborne disease. Similar technology is used to sterilize medical devices so they can be used in surgery or implanted without risk of infection. The effects of irradiation on the food and on animals and people eating irradiated food have been studied extensively. These studies show clearly that when irradiation...

Food Irradiation

Food irradiation is a food safety technology that can eliminate disease-causing germs from foods. Like pasteurization of milk, and pressure-cooking of canned foods, treating food with ionizing radiation can kill bacteria that would otherwise cause food borne disease. The process can also control insects and parasites, reduce spoilage, and inhibit ripening and sprouting. (5) The effects of irradiation on the food and on animals and people eating irradiated food have been studied extensively...

leading cause of lung cancer deaths following cigarette smoking (EPA). This phantom is the radioactive gas called Radon. Interestingly radon is a form of radiation that is a natural part of our environment. Radiation has always been in the Earth's atmosphere and without it life could not exist. However, too much radiation is lethal (Cole 7). Radiation can be a useful tool under controlled conditions such as in x-rays and cancer therapy. In some parts of Europe areas with high radon levels are thought...
