Radiation Definition and Examples

Radiation and radioactivity are two easily confused concepts. Just remember, a substance does not need to be radioactive to emit radiation. Lets look at the definition of radiation and see how it differs from radioactivity. Radiation Definition Radiation is the emission and propagation of energy in the form of waves, rays or particles. There are three main types of radiation: Non-ionizing radiation: This is the release of energy from the lower-energy region of the electromagnetic spectrum. Sources of non-ionizing radiation include light, radio, microwaves, infrared (heat), and ultraviolet light.Ionizing radiation: This is radiation with sufficient energy to remove an electron from an atomic orbital, forming an ion. Ionizing radiation includes x-ray, gamma rays, alpha particles, and beta particles.Neutrons: Neutrons are particles found in the atomic nucleus. When they break away from the nucleus, they have energy and act as radiation. Examples of Radiation Radiation includes emanation of any portion of the electromagnetic spectrum, plus it includes the release of particles. Examples include: A burning candle emits radiation in the form of heat and light.The Sun emits radiation in the form of light, heat, and particles.Uranium-238 decaying into Thorium-234 emits radiation in the form of alpha particles.Electrons dropping from one energy state to a lower state emit radiation in the form of a photon. Difference Between Radiation and Radioactivity Radiation is the release of energy, whether it takes the form of waves or particles. Radioactivity refers to the decay or splitting of an atomic nucleus. A radioactive material releases radiation when it decays. Examples of decay include alpha decay, beta decay, gamma decay, neutron release, and spontaneous fission. All radioactive isotopes release radiation, but not all radiation comes from radioactivity.

An Education In Language - 3188 Words

An Education in Language by R. RODRIGUEZ Born in 1944 in San Francisco, California, Richard Rodriguez grew up in a home in which Spanish was the first language; consequently, like millions of Americans he learned English as his second language. As a child, Rodriguez experienced an oftimes painful struggle to master English, which he calls his â€Å"public† language. As an adult, he attended Stanford University in California and Columbia University in New York, following which he did graduate work at the Warburg Institute in London and the Uni ­versity of California at Berkeley. Best known as a writer and lecturer, Rodriguez cur ­rently lives in San Francisco. Some educationists have recently told me that I received a very bad education.

Even our parents grew easier in public, following the Americanization of their children. My mother started referring to neighbors by name. My father continued to speak about gringos, but the word was no longer charged with bitterness and suspicion. Hearing it sometimes, I wasn’t even sure if my father was say ­ing the Spanish word, gringo, or saying, gringo, in English. Our house was no longer noisy. And for that I blamed my mother and father, since they had encouraged our classroom success. I flaunted my second-grade knowledge as a kind of punishment. (â€Å"Two negatives make a positive!†) But this anger was spent after several months, replaced by a feeling of guilt as school became more and more important to me. Increasingly successful in c lass, I would come home a troubled son, aware that education was making me different from my parents. Sadly I would listen as my mother or father tried unsuccessfully (laughing self-consciously) to help my brothers with homework assignments. My teachers became the new figures of authority in my life. I began imitating their accents. I trusted their every direction. Each book they told me to read, I read and then waited for them to tell me which books I enjoyed. Their most casual opinions I adopt ­ed. I stayed after school â€Å"to help† – to get their attention. It was their encouragement that mattered to me.Show MoreRelatedLanguage Education And The Language Classroom Essay1264 Words   |  6 PagesAs a language teacher and researcher, I am always on the lookout for useful books which draw not only on current theoretical issues, but also on pedagogical knowledge for the language classroom.

Human Rights Analysis Free Answers to Students-Myassignmenthelp

Question: Discuss about the Human Rights Analysis. Answer: The following essay is going to address the issue of human rights as it has been discussed in the provided case study. The topic seems to be hovering around the issues on double standard and hate speech. Since the4 social complexity is rising vehemently, and the social activists are on the mode of such understanding level, it has the opportunity of the senses which has been taking part in all sorts of formative activism. The essay has two parts. The first part is going to address the issues as indicated in the most respective genre of human rights and its generalising powers. It is going to be a discussion thread and the second part is going to analyse the details of the provided case study. There are certain level of critical understanding of the case analysis on double standard and hate speech. These two issues are extremely violent and conflicting while dealing with human being and his social interference. Creation of Thread Discussion: In general sense, threads are created in order to design a conversation level that has discussions on the topic and reply according to the concept building process. Following is the structure of thread that has constituted posting details on argumentative discussion on the double standard and human rights related issues. Student 1 Initial response to the Case Topic: While responding to the topic of discussion I have determined to carry on with the fact that my understanding on the subject hate speech and double standards is quite negative. I do not think that a person should be engaged in the position to raise his or her voice on the basis of religion. There are much more serious issues that can be dealt with. I have recently gone through two of the videos that portrayed outrageous speech of two different religious preachers and practitioners from two major Asian countries Bangladesh and India. Both of the countries have been in news for recent days because of constant growth of some sensitive issues regarding religious difference and conflict. Constant growth of religious difference and hatred between two of the major Asian religions- Hinduism and Islam has been quite outrageous in recent days when an Islamic clergy from Bangladesh disgraced his religious compatriot for attending so called Hindu festival poila baishakh- the New Year for the Be ngali community. On the other hand, several places in India is frequented by the Hindu armed forces who are supposed to celebrate Ram Navami- another Hindu festival. In these two scattered case, hate speech against each other has raised agitation among people against the other religions. Is this a state of country or a world that is called democracy? I do not think so because the entire world seems to be moving backward and people are sitting without a voice against the vehement practice. Reply from Student 2: In this case I have a say that most of the religious factors are not responsible. I think that most of the religious figures- especially the extremists are not ready to acknowledge the fair existence of the other religions. Religion is no longer limited to human race. It has rather extended its view to racism and gender bias. Hence we face such complexity in the modern age. How could one forget the Christian rage upon the Jews during Nazi period? Student 1 Reply: You may seem right, though there is no direct provision of involvement in religious aspect. Student 2 Reply: I do not agree to it at all because the first and the foremost cause of such hate speech is the counter version or reverse attack of what they have been undergoing for decades and centuries. People have a mindset that a particular religious group has proven themselves as vehement. Student 1 reply: This is because most of the cases the media does not play an unbiased role. As the media has the problem to b e biased and human right is not properly projected they are bound to create a misconception pertaining to this proble. Student 2 Reply: Yet, I think that this problem needs to be critically reviewed and addressed to a greater level so that a better world can be revived. Student 1reply: Agreed! A Reflective Insight on Hate Speech and Double Standard The European legal treatment of Islamophobic as well as homophobic speech does the illustration of the two horns of the impasse that the democratic states are facing to forbid hateful speech. From the perspective of U.S. First Amendment, the European approach to speech is having the involvement of Islam specifically, which is representing a worst-of-both-worlds standpoint, whereas regarding the extension of their approach in regard to racist hate speech, European legislators as well as judges have banned anti-Muslim as well as pro-terrorism speech (Khan 2015). Prosecuting the right-wing extremists to say or write matters that lack direct provocations towards violence are having certain probable negative aspects that have been reflected upon by other scholars. Such prosecutions might be having the propensity for turning the haters into victims as well as martyrs, and they might at times do the driving of hate institutions underground in ways that makes it very tough in monitoring them. The counter-balancing of these downsides are done by the significant symbolic message that are targeted by the full as well as equal polity members, who receive safety as well as status from the state. But, a negative aspect in this context is associated with the other vulnerable groups, which even though get targeted by hateful speech have not been banned, are still not full and equal members (Hasan 2015). Irrespective of the changes that occurred in the legislation such as the 2006 Racial and Religious Hatred Act in Britain, the years that followed Danish cartoons publication in 2005 did the witnessing of virtually no success in respect of appeals from Muslims towards national and global legal establishments for restricting the publication of the Prophets caricatures. Muslim governments as well as NGOs are continuously trying to do the persuasion of Western states for including Islam within the protective domain of their present laws regarding blasphemy or hate speech or creating a new legal aspect of religious insult or religious defamation. However, Danish prosecutors declined for inducting the editors or cartoonists at Fyllands-Posten in respect of speech that was associated with blasphemy or hate. Moreover, the Danish courts also did the rejection of a private complaint regarding defamation (Khiabany 2015). In fact, after the January 2015 terrorist attack on the offices of Charlie Hebdo as well as a Kosher grocery store in Paris, there occurred the juxtaposition of the French celebration regarding the right of the magazine in mocking the powerful as well as powerless in a similar way. In this context, it can be stated that the speech related prosecution of the French Islamists did the predation of both the Charlie Hebdo attacks as well as the 2014 anti-terrorism law. Hence, the signal sent by the legal responses states that the European society members are having the freedom for mocking Islam but not advocating radical Islamism (McGEE 2015). In the same manner, the Europeans are having the freedom for mocking Islam but not mocking minorities based on race. The Muslims in Europe have constantly raised their objection regarding a double standard. Human rights in many countries are complex and contentious. There may be a debate over the rights and responsibilities of citizens in a country. Countries have various laws pertaining to expressions of hate speeches against religions, races or other nations. However the matter faces different treatment in different country. For example, in Australia expression of hatred towards someone elses race, religion or caste is not serious an offence enough to be punishable by law. Even the Australian Human Rights Commission does not have the power to take an action against the agitator if no complaint is lodged. The victim is required to initiate the process by lodging a complaint the person. There are once again several extents to which these complaints go. While some complainants do not advance much further while there are cases which reach the court and cause much debate. Australia, though home to people of several origins does not deal with racist or hateful comments strictly. Less than 2 % complaints are tried or backed by court order and most of them are mediated by either removal of the hateful materials or seeking an apology (sbs.com.au 2017). The United Kingdom has stringent laws dealing with hatred speeches involving caste, race, religion, nationality and other individual aspect. The Public Order Act 1986 recognises comments condemning a person race, colour, nationality or ethnic origins. The person who threatens, abuses or expression racial hatred is liable with a maximum sentence of seven years, fine or both. The Criminal Justice and Public Order Act 1994 imposes a sentence of six, fine or both. However, all hateful speeches may not be dealt with strictly in the country. Dale McAlpine, a Christian preacher was arrested for preaching homosexuality a sin on April 20, 2010. However, the jury decided not be prosecute the person and the police paid him compensation for arresting him. This action or treatment of a person spreading hate speech clearly goes against the British laws enacted to protect the dignities of its population with diverse origins. The freedom of speech is guaranteed in France to all citizens TheLaw on the Freedom of the Press of 29 July 1881. The freedom to express does not empower a person to spread comments or speeches targeting other persons race, religion, ethnicity, physical deformity or any other attribute. It is both a civil and criminal office which attracts a year of imprisonment, a fine of 45000 or both. The Gayssot Act 1990 empowers a person to file a case if he considers articles in newspaper or any other print media hurts his sentiments. The Gayssot Act awards a person with a jail sentence for 5 years and 45000 for trying to demean the harm on Human rights inflicted by the Nazis during the World War II. For example, in 1974 a judge prohibited a poster of a film showing a half clad woman crucified to a cross which hurt the sentiments of the Christians. This showed that unlike Britain and Australia, the French authority is stricter when it comes to protection of human rights. Reference Bonotti, M., 2017.
