Measurement of the amount of material in a body. Different units of measure are used depending on what aspect of radiation is being measured. Absorbed dose is used in the calculation of dose uptake in living tissue in both radiation protection reduction of harmful effects and radiology potential beneficial effects for example in cancer treatment. The rad is the traditional unit of absorbed dose. One rad equals the dose delivered to an object of 100 ergs of energy per gram of material. It is also used to directly compare the effect of radiation. It is usually expressed as the amount of chemical administered eg milligrams per 100 grams for smaller animals or per kilogram for bigger test subjects of the body weight of the test animal.
It is being replaced by the unit gray gy which is equivalent to 100 rad. A measure of the total amount of material in a body. First choose the material you want to measure the static charge. For example the amount of radiation being given off or emitted by a radioactive material is measured using the conventional unit curie ci named for the famed scientist marie curie or the si unit becquerel bq. A space knowledge trivia quiz. This is the question and answer for space wordz level 12 with cheats solution hints for iphone and this game is developed by adrenaline punch.
Some good materials to test are hair carpet a cotton t shirt a polyester t shirt and a ceramic tile. Total suspended solids on the other hand are a total quantity measurement of solid material per volume of water 6. Body pressure measurement system bpms measures the pressure distribution of a human body on support surfaces such as seats mattresses cushions and backrests. The bod value is most commonly expressed in milligrams of oxygen consumed per litre of sample during 5 days of incubation at 20 c and is often used as a. Absorbed dose is a dose quantity which is the measure of the energy deposited in matter by ionizing radiation per unit mass. This means that tss is a specific measurement of all suspended solids organic and inorganic by mass.
The ld 50 is one way to measure the short term poisoning potential acute toxicity of a material. It is a measure of the amount of energy absorbed by the body. Temperature is the measure in degrees kelvin of the average kinetic energy of the atoms and molecules of a material. Toxicologists can use many kinds of animals but most often testing is done with rats and mice. Rub the balloon 5 times across the surface of a material. Demanded by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period.
Biochemical oxygen demand bod is the amount of dissolved oxygen needed ie. Tss includes settleable solids and is the direct measurement of the total solids present in a water body.
