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

geometry. Procedure and Observations Part 1a): In the first part of the experiment the EGS code was configured to calculate the influence of voxel size and the number of photons on the amount of radiation dose deposited on a water phantom. A mono-energetic source of 2MeV with a radius of 2cm was chosen to be the particle beam. A trial with 1million particles incident on a water phantom at a voxel resolution of 1cm was simulated then another trial

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

When Charles Wiley first opened his small printing shop in lower Manhattan in 1807‚ it was a generation of boundless potential searching for an identity. And we were there‚ helping to define a new American literary tradition. Over half a century later‚ in the midst of the Second Industrial Revolution‚ it was a generation focused on building

Responsibility‚ accountability and liability are issues that are raised by radiation technology. In this case we see that the carelessness or laziness of the medical technician‚ the lack of training in the handling of the equipment (software)‚ also of the maintenance of the updates of the software can cause the life a person.

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 November 2011‚ there were more than 6 billion subscriptions worldwide.[1] Mobile phones use electromagnetic radiation in the microwave range. Other digital wireless systems‚ such as data communication networks‚ produce similar radiation. In 2011‚ International Agency for Research on Cancer (IARC) classified mobile phone radiation as Group

Data Analysis Does radiation affect the growth of seeds? If‚ plant seeds are exposed to microwave radiation‚ then the seeds will grow less than how a seed is usually grown. The independent variable was the amount of microwave radiation the seeds receive. The dependent variable was the growth of the plant seeds. Control variables were the amount of water (30 mL at a time)‚ the amount of light (11 hours each day)‚ and the amount of seeds. The control group was the non-microwaved seeds. The experimental

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
