The effectiveness of KI as a specific blocker of thyroid radioiodine uptake is well established. When administered in the recommended dose, KI is effective in reducing the risk of thyroid cancer in individuals or populations at risk for inhalation or ingestion of radioiodines. KI floods the thyroid with non-radioactive iodine and prevents the uptake of the radioactive molecules, which are subsequently excreted in the urine.

It is advisable to check potassium levels about 2 weeks after beginning cesium, and then repeat it every two to four weeks. It is imperative that if you experience heart palpitations you have your potassium checked immediately. See similar questions...

Epiphyte's Delight is specially formulated for plants that do not need soil to grow. Nitrogen is the fertilizer component that promotes foliar growth and in many, if not most, fertilizers it is made from urea. This is fine except that this urea based nitrogen needs bacteria in soil to break it down into ammoniacal or nitrate nitrogen so that plants can use it. Since Tillandsias don't have soil, the urea nitrogen isn't broken down into the other forms and therefore the Tillandsias can't use it. See similar questions...

The pH needs to be in a proper range in order for the nutrients to be available to the plant. The optimum soil pH for boxwood is between 6.5 and 7.2. If the pH is below the recommended range, add dolomitic lime. This lime has low oxide content and will persist in the soil for 4‑7 years depending on application rates and soil type. If the pH is above 7.5, then lowering the pH would be in order. This is accomplished by adding iron sulfate. See similar questions...

The granddaddy of soil elements is potassium. Potassium is the "Cation for Anions". No, we are not turning this discussion into a chemistry class. We're just quoting a world famous botanist, who said that potassium is the locomotive which pulls the other elements around the plant and helps maintain electrical balance within the cell. Potassium is the water pressure regulator of the plant kingdom. See similar questions...

A State considering the use of potassium iodide would at least review the regulation (66 FR 5427; January 19, 2001 ), the Federal Policy on the Use of Potassium Iodide, the Food and Drug Administration (FDA) guidelines "Potassium Iodide as a Thyroid Blocking Agent in Radiation Emergencies," the FEMA guidelines, and the NRC disclaimer, and would briefly deliberate the State's position on the use of potassium iodide by the general public in the unlikely event of a severe nuclear reactor .

Answer: To control weeds, you can over-seed your lawn twice a year (early spring & early fall) to help prevent weed growth. Mowing your lawn high (4-inches or more) shades out most weed seeds and prevents them from germinating, while also slowing growth (for less frequent mowing) and strengthening the immune system of the grass. Keeping your grass unstressed by providing proper light, water, and nutrients will produce a crop of very thick turf. See similar questions...

When you see 30-10-10 this means you have 30% Nitrogen (N), 10% Phosphorus (P), and 10% Potassium (K). High nitrogen fertilizer is needed for orchids grown in bark, since bark tends to rob the plant of nitrogen. See similar questions...

Each time you plant in the EarthBox, use two cups of a dry granular fertilizer or plant food for vegetables. The three numbers of the elements making up the fertilizer content should be in the range of 5 to 15; i.e., 12-8-10, 10-10-10. After you have applied the fertilizer stripe, no additional fertilizer will be needed. See similar questions...

Potassium iodide (KI) should only be taken in a radiation emergency that involves the release of radioactive iodine, such as an accident at a nuclear power plant or the explosion of a nuclear bomb. A “dirty bomb” most likely will not contain radioactive iodine. A person who is internally contaminated with radioactive iodine may experience thyroid disease later in life. The thyroid gland will absorb radioactive iodine and may develop cancer or abnormal growths later on. See similar questions...

First, K+ is involved in the repolarization of the muscle membrane during an action potential. If the K+ concentration is low within the cell, the driving force on K+ is lower, and the repolarization is slower. This will have no effect on the absolute refractory period of the action potential (the time when it is impossible to initiate another action potential), but the muscle cell will be more depolarized than usual following the absolute refractory period and thus closer to the AP threshold.

The minimum potassium requirement for adults is approximately 1600 to 2000 milligrams per day. The potassium content of Nu-Salt® is 528 milligrams per 1/8 tsp. serving which is approximately the same as the amount of potassium in one medium banana or one cup of fresh cantaloupe. Potassium is used as a substitute for sodium and to enhance the flavor of Nu-Salt®. See similar questions...

No. Generally, water softeners can use either. With potassium chloride, you will use more material than with salt. Is it true that salt kills bacteria? I do not want the level of "good" bacteria in my septic system to be affected. VERY high concentrations of salt can kill some bacteria. However, the concentration of salt that is used in a softener is NEVER high enough to kill bacteria in septic systems. See similar questions...

A complete fertilizer simply means it contains the major (macro) nutrients nitrogen, phosphorus, and potassium. Prominently displayed on the front of any complete fertilizer package are three numbers. These numbers refer to the percentage of nitrogen, phosphorus, and potassium respectively. The most common ratio sold for roses is a 1-2-1 ratio, for example 5-10-5. See similar questions...

This is a tough one to answer, because fertilization is so tremendously tied to water quality, potting medium, temperature, light and a variety of other factors. However, if you just have a few plants, and don't want to fuss around a lot learning about the intricacies of water and fertilizer, I'd simply suggest you get any reasonably balanced 'orchid' fertilizer, that is low in urea, and use it at approximately 1/4 to1/2 the label strength every other watering.

Answer: All or most of the ingredients found in a natural-based fertilizer are natural ingredients that are derived from natural sources ? ingredients you will recognize when you read the label. These fertilizers do not contain herbicides, fungicides or insecticides ? they are not weed and feed products. Neither do they use fast-acting nitrogen that quickly leaches through the soil and into the water table, or runs off the surface of soil into streams and lakes. See similar questions...

Answer: No. While both products will feed your lawn, natural-based fertilizers are not formulated to kill weeds. The problem with indiscriminate use of weed & feed products is that it can accidentally kill broad-leaf plants you want to grow, such as trees. Some of the chemicals used in these products can also harm soil microorganisms, which are necessary for healthy soil. See similar questions...
