Effect of Ionizing Radiation on the Germination‚ Growth and Development of Corn (Zea mays L.) Alexis A. Parco BIO30 Group 1 Sec. A-6L September 27‚ 2012 ABSTRACT Corn seeds pre-exposed to 10‚ 30‚ and 50 kiloRads (kR) of radiation were grown in plots for almost 7 weeks. Four different setups – 10kR‚ 30kR‚ 50kR and the control‚ each with 10 corn seeds initially planted – were observed three times a week (during Mondays‚ Wednesdays and Fridays)‚ and the height of each growing corn was

“Solar Radiation and its Effects on Planet Earth” The Sun emits a tremendous amount of energy‚ in the form of electromagnetic radiation‚ into space. If we could somehow build a gigantic ball around the Sun that completely enclosed it‚ and lined that ball with perfectly efficient photovoltaic solar panels‚ we could capture all of that energy and convert it to electricity and be set in terms of Earth ’s energy needs for a very long time. Lacking such a fanciful sphere‚ most of the Sun ’s energy

The Impact of DNA on Criminal Investigations Science has become a very valuable tool for law enforcement. scientific evidence is used every day in criminal and civil courts throughout the United States; helping to Solve particularly difficult cases where all other investigative techniques have failed‚ provide clues where there are no witnesses‚ reduce the number of wrongful arrests‚ increase the reliability of evidence. Link together cases that otherwise could not be connected‚ such as local

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

Radiation Exposure Do you know much radiation you are exposed to everyday? Many people are not aware of the radiation levels around them on a daily basis. I believe that exposure to radiation should be minimal. I think protection and prevention is vital. Being aware of the health risks and what can be done to protect yourself should be a well known piece of knowledge. If followed‚ this knowledge can help reduce radiation exposure levels. Exposure to radiation is higher today than it has ever

Radiation Therapy What is radiation therapy? According to wikipedia Radiation therapy discovered in 1889 also known as radiotherapy‚ radiation oncology‚ or XRT‚ is the medical use of ionizing radiation as a part of cancer treatment to control malignant cells. Radiotherapy may be used for curative or adjuvant cancer treatment‚ with curative being the cure and adjuvant being additional treatment. Radiation therapy can also be used as palliative treatment‚ which is where a cure is not possible and

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

The effect of mobile phone radiation on human health is the subject of recent interest and study‚ as a result of the enormous increase in mobile phone usage throughout the world (as of June 2009‚ there were more than 4.3 billion users worldwide). Mobile phones use electromagnetic in the microwave range. Other digital wireless systems‚ such as data communication networks‚ produce similar radiation. The WHO has classified mobile phone radiation on the IARC scale into Group 2B - possibly carcinogenic

DNA DNA‚ or Deoxyribonucleic Acid‚ is described‚ in Encarta Encyclopedia as a genetic material of all cellular organisms and most viruses. DNA carries the information needed to direct protein synthesis and replication. Protein synthesis is the production of the proteins needed by the cell or virus for its activities and development. Replication is the process by which DNA copies itself for each descendant cell or virus‚ passing on the information needed for protein synthesis. In most cellular

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 energy
