Which of the following units of measuring radiation dosage accounts for potential tissue damage? View Available Hint(s) Hint 1. A point to consider This unit takes into consideration the biological effectiveness (RBE) of the dose. O roentgen • rad OGy O rem Submit Request Answer
Jack was exposed to fast neutrons; he received a radiation dose of 120 rem on part of his hand, affecting 30.0 grams of tissue. The relative biological effectiveness (RBE) of these neutrons is 10.0. How much radiation did Jack receive? Express your answer in rads to three significant figures. What was the total energy of the radiation Jack received?Suppose Jill received the same rad dosage, but from beta rays with an RBE of 1.10 instead of from neutrons. What is...
True or false
x12. Tissues with a rapid turnover are most vulnerable to radiation damage Tissues sensitive to radiation damage include hair follicles, bone marrow and gastrointestinal mucosa
7. Within the cell the most important critical target molecule for producing radiation damage that is lethal or mutagenic to cells is 8 & 9.For any type of imaging using ionizing forms of radiation, in general as the speed of image reception and diagnostic quality of the image necessitating a balance be maintained between exposure and diagnostic quality increases the amount of radiation exposure requirements. Act of 1990 requires the reporting of accidents due to malfunction from 10. The FDA...
State the most common ways humans get infected with fungi. What are the medications that are used for fungal treatment diseases.
Empirical results have revealed that for every unit of radiation
dose (1 rad) there are 5 ✕ 1011 inactivating events per
cubic centimetre treated.
(a)If one were to administer a dose of 12 millirads, how many
inactivating events per cubic centimetre would this dose
produce?
inactivating events per cubic centimetre
(b)The approximate volume of a cell is estimated to be
10−11 cm3. Calculate the fraction of the
cells of the tissue treated by X-rays that will be hit if we...
Outline the evolutionary history of humans since the most recent common ancestor with chimps. What are the major traits that distinguish us from chimps and our common ancestors? What environmental changes occurred? What dietary changes occurred? Locomotion, tools, and language? ASAP pleaseeeeeeeeee
20. A rad is defined as: a the ratio of the dose of x or gamma radiation to the dose of alpha particles needed to produce a specific biologic effect. b. 100 ergs of energy being absorbed per gram of absorbing material. c. REM X RBE d. one electrostatic unit of charge per milliliter of dry air at STP 27. The total counts injected into a patient undergoing a plasma volume were 5.2 x 10 cpm. A 5 ml plasma...
1. (15 pt) Electric dipole field Oscillating charges produce electromagnetic radiation. The most common antenna is the dipole antenna. Here you will derive the static dipole field at a particular point in space. (a) (8 pt) Find the electric field (magnitude,tq and direction) at point P due to the d2 charges in the figure. Assume free space. d/2 (b) (5 pt) Simplify the expression for the case of rd and write your expression d2 in terms of the magnitude of...
#3 One of the most common ways of measuring intelligence is the IQ test. IQ scores in the US population have an average of µ = 100 and a standard deviation of σ = 15. Suppose a researcher wanted to test whether socioeconomic status (SES) has an effect on IQ scores. The researcher takes a random sample of n = 100 people, selected from a list of the 1000 richest people in the United States. a. Based on this information,...
