The radiation weighting factor for a type of radiation can be considered as a weighting relating the absorbed dose to biological effect.Dose equivalent = absorbed dose x radiation weighting factorThe higher the radiation weighting factor, the greater the biological impact an absorbed dose will have on the patient. Rank these types of radiation in terms of their radiation weighting factors from lowest to highest.N.B. In the textbook, radiation weighting factor is referred to as quality factor, however this is an older term.Group of answer choices1st (Lowest)2nd3rd (Highest)

Some tissues are more sensitive to radiation than others, so an adjustment to the dose equivalent is necessary to reflect the relative risk of damage to various tissues from radiation exposure. The adjustment applied to the value of the dose equivalent is called the tissue weighting factor.Rank the following tissues from least (1) to most (3) susceptible to radiation damage.Group of answer choices123

Which of these quantities impacts on the equivalent dose? Select all that apply. Marks will be deducted for any incorrect responses.Group of answer choicesAbility of the tissue to absorb the radiationThe degree to which the particular type of radiation can cause biological damageEnergy flux of the incident radiationTime over which the radiation is applied

Specify the relationship between the mass and charge of radiation and its ionising ability. The greater the mass and charge, the greater the ionising ability.1The smaller the mass and the greater the charge, the greater the ionising ability.2The greater the mass and the smaller the charge, the greater the ionising ability.

(d) Which of the following factors determine the impact of exposure to radioactivity? A. Distance from source B. Duration of exposure C. Type of radiation D. All of the above

Radiation can be classified as either ionising or non-ionising radiation. Ionising radiation is the radiation that causes biological damage. What is the attribute of the radiation that defines whether it is ionising or not?Group of answer choicesThe ability to remove electrons from atomsWhether the radiation is as a particle or a waveThe length of exposure to the radiationThe intensity of the radiation
