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

Concepts of Radiation Radiation * Emission of energy from an atom and the transmission of this energy through space. * Energy propagated in a material medium or space. * Energy in transit. What are the types of radiation? * Radiation is of two general types in our environment. * They are called non-ionizing and ionizing. Ionization * the energy transferred to the electrons causes them to be pulled away or removed from an atom entirely. * The result is the

Gamma Rays in Radiotherapy 8B Lae Eun Kim In this unit‚ we learned that there are 7 types of radiation of the electromagnetic spectrum – gamma rays‚ x-rays‚ ultraviolet‚ visible spectrum‚ infrared‚ microwaves and radio waves. With different wavelengths‚ they each have different properties and uses. Gamma rays are the radiation with the smallest wavelengths – 10-12m to 10-10m – and the most energy and the most danger of any wave in the electromagnetic spectrum. Radiotherapy‚ a treatment the use

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

The Biological Effects of Radiation Whether the source of radiation is natural or man made‚ whether it is a small dose of radiation or a large dose‚ there will be some biological effects. Radiation causes ionizations of atoms‚ which will affect molecules‚ which may affect cells‚ which may affect tissues‚ and so on. Although most people tend to think of biological effects in terms of the effect of radiation on living cells‚ in actuality‚ ionizing radiation‚ by definition‚ interacts only with

INTRODUCTION Radiation‚ flow of atomic and subatomic particles and of waves‚ such as those that characterize heat rays‚ light rays‚ and X rays. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. This article delineates the properties and behaviour of radiation and the matter with which it interacts and describes how energy is transferred from radiation to its surroundings. Considerable attention is devoted to the consequences of such an energy

We hypothesized that the amount of UV radiation exposed has a negative correlation with yeast genetic stability‚ which ultimately determines the number of yeast colonies. In this experiment‚ yeast cells were treated with UV radiation‚ protected by photoprotective agents with different strength (in ascending order: Sunscreen #2‚ #1‚ aluminium foil). After letting it grow for seven days at 37 degrees‚ some grown colonies were counted to determine the effectiveness of photoprotective agents. After comparing

2012) Exposure to UV radiation is the leading cause of most skin cancers as it induces DNA damage in skin cells. The effects of UV radiation can be classified based on the amount of exposure as acute or chronic. Acute side effects include sunburns and chronic effects can be mutagenic and also increase aging in humans. (Pacholczyk‚ 2015) The effects of UV radiation are significant and finding
