The Radiation Calculator was developed to help you learn about the many types of imaging studies that use radiation and also track the amount of your radiation exposure. Please Note: This app is NOT a substitute for medical advice. Talk with your doctor about the risks and benefits of any imaging study, whether there are any other alternatives, and if you have questions or concerns about your radiation exposure.

By entering your age and information about your imaging test history, you can calculate your estimated radiation exposure over time and compare the amount of radiation you have received with an average patient within the age range you entered. You can also compare this amount to radiation totals received through natural and other sources.

The Radiation Calculator has many great features:

* Explanation of imaging studies and estimated radiation dose
* Easy-to-use calculator to determine your estimated radiation exposure from imaging studies
* Customizable radiation exposure report that can be saved to share with your doctor
* Comparison of estimated radiation dose from imaging studies and other sources of radiation

Great app


As a radiation safety professional, this is exactly the type of app I would like to see doctors and patients to make use of to help visualize a (rough) estimate of the radiation dose from medical imaging. Of particular use is the comparison of the dose from imaging to both the average annual dose and the average dose from natural background. The estimates are based on the current standard reports for the field, BIER VII, and appear to be reasonable estimates from what I have seen. Good Job!

Chem Class


My chemistry teacher had us download this app for our radiation unit. It was interesting, but I wish it would include things like air travel and such. Otherwise okay job.

No Information


This app collects data on radiation tests that have been taken, and the default setting is that the information that you supply is saved. The app does not show any information based on the data that is collected.
