Barium enters your body when you breathe air, eat food, or drink water containing barium. It may also enter your body to a small extent when you have direct skin contact with barium compounds. The amount of barium that enters the bloodstream after you breathe, eat, or drink it depends on the barium compound.

The name of BaCO3 is barium carbonate. Ba+2 is the barium ion, which results from a barium atom losing two electrons. Carbonate is a polyatomic ion…

Strong Electrolytes: Essentially all ionic compounds and the strong acids. (Example: BaCO3) Weak Electrolytes: Molecular compounds that partially dissociate, which are primarily weak acids and bases. The weak acids include most all acids, and the weak bases include all the non- hydroxide bases.

BaSO4, HgSO4 and PbSO4 are insoluble. A solution of barium chloride is mixed with a solution of potassium sulfate and a precipitate forms. Because it is insoluble in water we know that it is the precipitate. As all of the other substances are soluble in water we can rewrite the equation.

Barium (Ba), chemical element, one of the alkaline-earth metals of Group 2 (IIa) of the periodic table. The element is used in metallurgy, and its compounds are used in pyrotechnics, petroleum production, and radiology. Properties of barium.

Barium swallow is a safe test. But there are possible risks. Your doctor makes sure the benefits of having the test outweigh the possible risks. A small amount of barium liquid can go into the airway when you drink it.

It is important to drink plenty of liquids during and after the test. Barium sulfate may cause severe constipation.

The barium swallow is a less invasive way to look at the upper GI tract than an endoscopy. Barium swallows are a useful diagnostic tool for checking for upper GI tract disorders that can be easily diagnosed with X-ray alone. More complex disorders require endoscopy.

Upper GI endoscopy can be used to identify many different diseases:

• gastroesophageal reflux disease.
• ulcers.
• cancer link.
• inflammation, or swelling.
• precancerous abnormalities such as Barrett’s esophagus.
• celiac disease.
• strictures or narrowing of the esophagus.
• blockages.

All endoscopic procedures involve some degree of sedation, which relaxes you and subdues your gag reflex. Being sedated during the procedure will put you into a moderate to deep sleep, so you will not feel any discomfort when the endoscope is inserted through the mouth and into the stomach.

Swallow studies generally result in an effective dose of roughly 1 mSv, which is reported in the literature for these examinations (Brenner and Huda 2008).

Modified Barium Swallow Studies (MBSSs) are a fluoroscopic exam that exposes patients to ionizing radiation. Even though radiation exposure from MBSSs is relatively small, it is necessary to understand the excess cancer risk to the patient, in order to ensure a high benefit-to-risk ratio from the exam.

“For adults, radiation exposure from modified barium swallow studies was very, very low,” said Bonilha. “On average, it was 0.2 millisieverts, which, for perspective, is a lesser amount of radiation than is emitted from a person’s body in a year and similar to that associated with living on earth for 32 days.

In the SI system, a millisievert (mSv) is defined as “the average accumulated background radiation dose to an individual for 1 year, exclusive of radon, in the United States.” 1 mSv is the dose produced by exposure to 1 milligray (mG) of radiation….

Some exposure does us no harm. However, when the radiation dose exceeds certain levels. Then it could pose a health risk. The annual limit for radiation dose for a member of the public is 1 mSv per annum or 1000 µSv per annum.

MSV

In sieverts (the measurement of radiation dosage), a banana produces approximately 98.2 nanosieverts (9.82 Sv to the -8 power).

According to the chart, the average person safely absorbs about 3.65 millisieverts (or 0.00365 sieverts) of radiation annually, through simple activities like living in a brick or concrete building (70 microsieverts a year) or sleeping next to another person (0.05 microsieverts).

A large banana has an activity of about 18.4 Bq (becquerel, equal to one disintegration or nuclear transformation per sec- ond), or 0.511 nCi (nanocuries).

To cause death within hours of exposure to radiation, the dose needs to be very high, 10Gy or higher, while 4-5Gy will kill within 60 days, and less than 1.5-2Gy will not be lethal in the short term. However all doses, no matter how small, carry a finite risk of cancer and other diseases.
