Radioactive Definitions and Effects for Health and Benefits in Agriculture
In this case the use of radioactive material, which is specifically radioactive radiation is based on the ability of radiation to cause changes such as ionizing the nucleus or molecules, breaking bonds between atoms so as to produce free radicals, making the nucleus or nucleons become radioactive and freeing up some heat energy.
To be able to be used effectively and efficiently, first identify to find out the type and amount of radiation to be used. This needs to be done because each type of radiation has unique characteristics so to determine its existence both in the type and amount of radiation it is also necessary to use methods and techniques that are also typical for each type of radiation.
Radioactive decay occurs in three main types - named alpha, beta and gamma decay with the first three-letter symbol of the Greek alphabet. Radioactive decay occurs in unstable atomic nuclei - those that do not have enough binding energy to hold the nucleus together due to excess either protons or neutrons, appearing in three main types - named alpha, beta and gamma decay with the first three letter symbol from the Greek alphabet.
Gamma radiation is the most million of the three and will be able to penetrate a few centimeters of lead. Beta particles will be absorbed by a few millimeters of aluminum while alpha particles will stop their tracks after a few centimeters of air or a piece of paper.
Effects on human health
There are two main health effects caused by radiation that act in the short and long term and also at shorter and greater distances. Radiation causes health problems by killing cells in the body and the amount and type of damage done depends on the radiation dose received and the time at which the dose was spread.
Radioactive materials that spread to a wider area can cause long-term health effects through prolonged exposure, especially if they enter the food chain or are inhaled or swallowed directly. Radioactive isotopes of iodine which undergo beta decay, can accumulate in the thyroid gland and can cause thyroid cancer.
Utilization in Agriculture
As for the utilization in agriculture which include:
Eradication of Homo With Infertile Male Techniques
Radiation can cause biological effects such as cabbage pests, in the laboratory are bred cabbage pests in the form of a considerable amount. The pest is then radiationed so that male insects become infertile. After that the pest is released in the area attacked by pests. It is hoped that a marriage between local pests and infertile males will be released, eggs from such marriages will not hatch. Thus the pest reproduction is disrupted and will reduce the population.
Plant breeding
Plant breeding or formation of superior seeds can be done using radiation. For example rice breeding, rice seedlings are given radiation with doses that vary from the smallest dose that does not carry the effect to a lethal low dose. The irradiated seeds are then planted and placed in a garden in groups according to the size of their radiation doses.
Food Storage
We know that foodstuffs such as potatoes and onions if stored a long time will sprout. Radiation can inhibit the growth of such materials. So before the material is stored in a given dose of radiation so it will not sprout thus can be stored longer.
Thus the discussion on "Radioactive" Definition & (Effects for Health - Benefits in Agriculture) hopefully with this review can add insight and knowledge of all of you, thank you very much for your visit.
Bioteknoloogi ini selain diterapakan didalam farmasi dan kedokteran dan pangan, juga bias diterapakan dalam bidang pertanian. Dalam pembuatan kompos dan biogas merupakan salah satu contoh yang sederhana dalam penerapan bioteknologi pertanian. Pemanfaatan bioteknologi pertanian pada zamam sekarang ini dilakukan dengan secara modern, berikut ini ada beberapa contoh dari bioteknologi pertanian.
Hydroponics and Aeroponics
Hydroponics is work by utilizing water. For methods used in hydroponics such as water culture using water media, sand culture methods using sand media and porous methods, among others, using gravel media and new brick fragments. With this sand method including successful and easy ways to apply.
The Advantages Of Using Hydroponics
Higher crop production
Use of fertilizer more efficiently
Does not depend on natural conditions
Plants are free from pests and diseases
Grow faster
Easy in the process
Does not require so much land
Fruits obtained by dihydroponics include cucumbers, paprika and lettuce, while plants that can be hydroponized are star fruit, guava water and melons.
Aeroponics is a type of hydroponics because water that contains nutrient solutions is sprayed in the form of mist to hit the roots of plants. The principle of the application of aeroponics is Styrofoam which is given planting holes with a distance of 15 cm, which is then using foam padding or rock wool, vegetable seedlings are embedded in the planting hole.
At the root of the plant will dangle freely downwards, then under the strands of Styrofoam there is a sprinkler or atomizer that emits a mist of nutrient solution up to the roots.
Plant Tissue Culture
Plant tissue culture is a method or technique in isolating plant parts namely cells, tissues, organs and protoplasms and growing them on artificial media in aseptic conditions in a controlled space so that the parts of these plants will grow and develop into complete plants.
The part that is grown through tissue culture is called an explant. Explants used are usually from young plant tissue, such as shoots, young leaves and root tips.
Various Types of Plant Tissue Culture
Antherculture pollen is a tissue culture technique using explants from stamens or pollen.
Cloroplast culture is a tissue culture technique using chloroplast explants for the purpose of improving the properties of plants by making new varieties.
Culture maristem is a tissue culture technique using explants or plant parts from young or meristem tissues.
Protoplast culture is a tissue culture technique using parts of protoplast plants or living cells that have been removed from the cell wall.
Somatic cross or crossing of the protoplasm is the crossing of two kinds of protoplasm into one, then cultivating it into a small plant with a new nature.
