In ancient Athens the citizens were : men (women were not considered citizens) who were native to the city (and whose paresnts and grandparents were native too) and who had served in the army.
Slaves, including freed slaves and foreigners were not citizens.
A few types of traditional games that American children play are things such as hide and seek, tag, baseball, hopscotch, skipping rope, and many others.
Further Explanation:
American children play many traditional games that have been passed down through generations. Children usually play in groups, pairs or by themselves. Listed below is more types of traditional games played in America.
- The floor is lava
- Cops and robbers
- Sardines
- Jumping jacks
- Marbles
- Bloody knuckles
- Video games
Most of these games are played outdoors, but can be played indoors also.

1. Tip: Do Not Procrastinate. Get your work done early and be efficient. People don’t think that freshman year doesn’t really matter or counts, but it does.
2. Tip: Get to know your teachers and counselors. Knowing a lot of adults in the school can give you more opportunities than you really believe. You’ll be known and well like by your fellow elders
3. Don’t be a stereotypical freshman. A lot of freshman try extra hard to act cool and that’s why upperclassman don’t really like them. Be you and don’t try to be someone you aren’t.
4.Do extracurriculars. You don’t have to do sports like many people do, but at least join a club. All of this will be great for your college application come senior year. If you don’t like the extracurriculars your school has then do activities outside of school. You could always add those to your application as well.
5. Have fun. Enjoy your freshman year as much as you can. Do the Snipity Snap, be on the gram, enjoy all of this while you can because it only gets harder from here on out.
People are exposed to natural radiation sources as well as human-made sources on a daily basis. Natural radiation comes from many sources including more than 60 naturally-occurring radioactive materials found in soil, water and air. Radon, a naturally-occurring gas, emanates from rock and soil and is the main source of natural radiation. Every day, people inhale and ingest radionuclides from air, food and water.
People are also exposed to natural radiation from cosmic rays, particularly at high altitude. On average, 80% of the annual dose of background radiation that a person receives is due to naturally occurring terrestrial and cosmic radiation sources. Background radiation levels vary geographically due to geological differences. Exposure in certain areas can be more than 200 times higher than the global average.
Human exposure to radiation also comes from human-made sources ranging from nuclear power generation to medical uses of radiation for diagnosis or treatment. Today, the most common human-made sources of ionizing radiation are medical devices, including X-ray machines.
Exposure to ionizing radiation
Radiation exposure may be internal or external, and can be acquired through various exposure pathways.
Internal exposure to ionizing radiation occurs when a radionuclide is inhaled, ingested or otherwise enters into the bloodstream (for example, by injection or through wounds). Internal exposure stops when the radionuclide is eliminated from the body, either spontaneously (such as through excreta) or as a result of a treatment.
External exposure may occur when airborne radioactive material (such as dust, liquid, or aerosols) is deposited on skin or clothes. This type of radioactive material can often be removed from the body by simply washing.
Exposure to ionizing radiation can also result from irradiation from an external source, such as medical radiation exposure from X-rays. External irradiation stops when the radiation source is shielded or when the person moves outside the radiation field.
People can be exposed to ionizing radiation under different circumstances, at home or in public places (public exposures), at their workplaces (occupational exposures), or in a medical setting (as are patients, caregivers, and volunteers).
Exposure to ionizing radiation can be classified into 3 exposure situations. The first, planned exposure situations, result from the deliberate introduction and operation of radiation sources with specific purposes, as is the case with the medical use of radiation for diagnosis or treatment of patients, or the use of radiation in industry or research. The second type of situation, existing exposures, is where exposure to radiation already exists, and a decision on control must be taken – for example, exposure to radon in homes or workplaces or exposure to natural background radiation from the environment. The last type, emergency exposure situations, result from unexpected events requiring prompt response such as nuclear accidents or malicious acts.
Medical use of radiation accounts for 98 % of the population dose contribution from all artificial sources, and represents 20% of the total population exposure. Annually worldwide, more than 3600 million diagnostic radiology examinations are performed, 37 million nuclear medicine procedures are carried out, and 7.5 million radiotherapy treatments are given.
Hope this helps
