|---|---|---|---|---|---|
| show | Direct (to the DNA or RNA)
🗑
|
||||
| show | Indirect
🗑
|
||||
| show | Indirect
🗑
|
||||
| show | Indirect
🗑
|
||||
| Will direct or indirect effects occur to routine X-ray exams? | show 🗑
|
||||
| show | Direct
🗑
|
||||
| show | Indirect
🗑
|
||||
| show | yes, but it still be cause latent damage such as cancer, abnormal functions
🗑
|
||||
| show | indirect
🗑
|
||||
| A double strand mutation would be caused by which type of interaction? | show 🗑
|
||||
| show | Alpha and Beta
🗑
|
||||
| show | X-ray photons and gamma
🗑
|
||||
| There is approximately ___% of DNA in the body | show 🗑
|
||||
| Why will indirect effects be the most likely result from an xray interaction? | show 🗑
|
||||
| Ionization of water cause what chemical in the water? | show 🗑
|
||||
| Free radicals contain an unstable ____________ shell electron | show 🗑
|
||||
| show | no, direct hits are to the DNA molecule itself and therefore no water molecule was affected
🗑
|
||||
| show | Nutrients and protein in the repair enzymes. Need oxygen for repairs.
🗑
|
||||
| Typical x-ray exam response is "nothing" | show 🗑
|
||||
| Direct hits will occur mostly with which type of combination: 1) High LET/High SI or 2) Low LET/Low SI | show 🗑
|
||||
| show | Low LET/Low SI
🗑
|
||||
| How are SI and LET related? | show 🗑
|
||||
| show | specific ionization. Pairs of ions that are transferred to tissue. The more pairs, more dense the energy is transferred, but shorter the distance it travels = more damage. Higher SI= Higher LET. Like a Tornado - concentrates damage in a small/short area.
🗑
|
||||
| Example of low SI | show 🗑
|
||||
| High RBE, High SI, High LET is an example of what radiation? | show 🗑
|
||||
| show | X-ray (quality factor of 1) - this is what is multiplied with absorbed dose from dosimeter to get your equivalent dose on your dosimetry report
🗑
|
||||
| OER ratio of 3 would be what type of energy? | show 🗑
|
||||
| show | Alpha or high LET. 1 means it is NOT sensitive from oxygenated tissue.
🗑
|
||||
| show | directly. Higher the QF, more damage. Alpha is 20 and creates more damage
🗑
|
||||
| show | inversely. A low RBE for xray, will equate to a higher number for OER for xray. (Xray: RBE 1, OER 3)
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
