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)

The publication gives different types of radiograph and their conversion factors: Head AP, Head PA, Head Lat, Cervical spine AP, Cervical spine Lat, Shoulder AP, Shoulder (axial), Chest PA, Chest Lat, Thoracic spine AP, Thoracic spine LAT, Lumbar spine AP, Lumbar spine Lat, Lumbo spine Lat, Lumbo-sacral joint Lat, Apdomen AP, Pelvis AP, Single Hip AP, Both Hips AP, Femur AP, Femur Lat, Knee AP, Knee Lat, Foot (dorsi-plantar), Foot (oblique)

  1. Is everything correct? Everywhere in the publications the effective dose for chest imaging is given as 0.02 mSv. But here in the calculator the values come out as 0.0002 mSv. Are the units wrong?

    1. Are you using point instead of comma? Also be careful about unit, you have to choose the right one. In DICOM DAP has dGy*cm2.

  2. I want to convert DAP of humerus to effective dose but It doesn’t have humerus to select so Can I select shoulder instead????

  3. Is an number that follow the protocol is conversion coefficient????

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. Note: use point in stead of comma as a decimal separator. Input value   from  mGy.cm2 cGy.cm2 dGy.cm2 Gy.cm2 uGy.m2 mGy.m2 Gy.m2 to  mGy.cm2 cGy.cm2 dGy.cm2 Gy.cm2 uGy.m2 mGy.m2 Gy.m2 Simple example with respect to unit conversions: When converting from Gy.cm2 to µGy.m2 the following reasoning can be followed: 1 Gy = 1,000,000 (1 million) µGy; 1 cm2 = 0.0001 m2; this means that 1 Gy.cm2 = 1,000,000*0.0001 µGy.m2 = 100 µGy.m2. Note that some conversions won't result in any change, for example: 1 cGy*cm2 = 1 µGy*m2. DAP values can be translated  into effective dose levels by multiplication using specific conversion factors. For this purpose it is important that DAP value and conversion factor match in terms of their units. The above DAP calcula

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.

DLP unit converter

With this converter, the dose length product (DLP) can be converted into corresponding values expressed by other units. Note: use point in stead of comma as a decimal separator. Input value   from     mGy.cm cGy.cm dGy.cm Gy.cm uGy.m mGy.m cGy.m dGy.m Gy.m to     mGy.cm cGy.cm dGy.cm Gy.cm uGy.m mGy.m cGy.m dGy.m Gy.m

Dose rate converter

Dose rate is defined as: the quotient of the dose over a given period of time, and this duration. For example, the dose rate can be expressed in units of Gy/h. This converter helps to convert dose rate into another unit. Input value   from  uGy/s uGy/m uGy/h mGy/s mGy/m mGy/h cGy/s > to  uGy/s uGy/m uGy/h mGy/s mGy/m mGy/h cGy/h >                                     ...or use SHARE button f
