Percentage calculator

In mathematics, a percentage (from Latin per centum "by a hundred") is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", or the abbreviations "pct.", "pct"; sometimes the abbreviation "pc" is also used. A percentage is a dimensionless number (pure number). See Wikipedia.

DAP unit converter

With this converter, the dose area product (DAP) can be converted into corresponding values expressed by other units. Use other tool for DAP to effective dose (mSv) conversion. (something else - check new tool: flight radiation calculator ) Note: use point in stead of comma as a decimal separator. DAP unit converter Type a value in the DAP field to convert to DAP in other units: DAP From mGy.cm2 cGy.cm2 dGy.cm2 Gy.cm2 μGy.m2 mGy.m2 Gy.m2 To mGy.cm2 cGy.cm2 dGy.cm2 Gy.cm2 μGy.m2 mGy.m2 Gy.m2 Result DAP Calculator developed for Blogger platform by Dr.Wizard . Simple example with respect to unit conversions: When converting from Gy.cm2 to µGy.m2 the following reasoning can be...

DAP to mSv converter - radiography

This tool calculates the effective dose (mSv) with respect to the DAP value (e.g. cGy.cm2) belonging to different types of radiograph . It does for instance, Gy.cm2 to mSv conversion. It is emphasized that the result is an estimation. The conversion factor relates to ICRP 103 and is obtained from: Radiation risks from medical x-ray examinations as a function of the age and sex of the patient, BF Wall et al., Report HPA-CRCE-028 (2011) ; www.hpa.org.uk Note: use point in stead of comma as a decimal separator. Input value dose area product (DAP) Gy.cm2 mGy.cm2 cGy.cm2 dGy.cm2 μGy.m2 ...

Dose area product (DAP)

Dose Area Product (DAP), is a multiplication of the dose and the area exposed, often expressed in Gy.cm2. Modern x-ray systems are fitted with a DAP meter, able to record accumulated DAP during an examination. A schematic of the imaging chain with DAP meter is given below. How is DAP measured? An ionization chamber larger than the area of the x-ray beam is placed just beyond the xray collimators. The DAP ionization chamber must intercept the entire x-ray field for an accurate reading. The DAP-value is depending on x-ray technique factors (kVp, mA, filtration) and time of the procedure and the area of the x-ray field. For example, a 5 x 5 cm x-ray field with an entrance dose of 1 mGy will yield a 25 mGy.cm2 DAP value. If the field is increased to 10 x 10 cm, with the same entrance dose of 1 mGy the DAP increases to 100 mGy-cm2, which is 4 times the DAP for the 5 x 5 cm field. Why DAP? Dose-area product is relatively easy to measure. DAP has been shown to correlate well ...

DLP to mSv converter

Here is a straightforward CT dose calculator for determining the Effective Dose (mSv) from the Dose Length Product (mGy cm) for a CT exam of a single organ. Type a value in the DLP field to convert to mSv effective dose: DLP DLP unit Gy.cm dGy.cm cGy.cm mGy.cm uGy.cm Patient 0 year old 1 year old 5 year old 10 year old adult Body region Head and Neck Head Neck Chest Abdomen and Pelvis Trunk k (mSv.mGy-1.cm-1) Effective dose (mSv) The values for the conversion factor that are used in the calculator are taken from the AAPM task group report on Radiation Dose Reporting .

Flight Radiation Calculator

Flight Radiation Dose Calculator Welcome to our simple and effective radiation dose calculator! Use this tool to quickly determine the Effective Dose (mSv) you receive during a flight. Whether you’re curious about radiation on a short domestic trip or a long-haul international flight, our calculator has you covered. How to Use Enter a value in the 'Flight Time (hours)' field to calculate the effective dose in millisieverts (mSv). Our calculator uses an average radiation dose of 0.004 mSv per hour , based on data from Wikipedia . For example: A 7-hour flight results in a dose of 0.028 mSv . Time of flight (hrs) Dose rate (mSv/h) Effective dose (mSv) More Information About Flight Radiation Where Does the Radiation Come From? The radiation you are exposed to during a flight primarily comes from cosmic radiation, which becomes more intense as you fly higher. At typical cruising altitudes of 30,000-35,000...
