Welcome to RADAR - the RAdiation Dose Assessment Resource

... now with 27% more 'clickedy' stuff than any other dosimetry site!

Welcome to the RADAR web site, in which we seek to provide information on dose assessment models and methods for the 21st century. Our goal is to bring together the various resources that exist in the areas of internal and external dose assessment, integrate them into a single system, and put them in your hands as quickly and efficiently as possible. In this new age of internet access to information, we want to make information from this particular area of science available as quickly as possible in a form that is easy for you to use. If a new model or method is proven to be of value and the results valid, it will appear as soon as possible on the RADAR. If you have a new model to propose, send it in for evaluation. If it's something needed by the user community and the results are sound, we'll put it on the RADAR.

RADAR Changes the Dosimetry World!

RADAR has updated the dosimetry world by replacing the old, 'stylized' dosimetry phantoms of the 1980s and 1990s:

...with image-based, voxelized models:

The new phantoms were used with various biokinetic models and the OLINDA/EXM 2.0 software code to produce two compendia of dose estimates for many radiopharmaceuticals, one for adults and pediatric subjects, and one for women at different stages of pregnancy.

Information about OLINDA/EXM 2.0 is found here.

RADAR members have now compiled a listing of over 1000 specific gamma ray constants, based on the recently released ICRP decay data series. Get a copy for you bad seff right heeeeeeeeeeeere.

Roentgen Shrugged! Why? You'll just have to read the Health Physics Newsletter article at this page to find out.

Check out the RADAR nuclear medicine patient exposure radiation dose calculator. It performs dose calcultions for release of radioactive nuclear medicine patients and dose from other related situations.

Updated plain film x-ray and CT dose data (from the CRCPD's NEXT-2007 report) in our handy dandy Dose/Risk Calculator for standard medical examinations

Is it SAFE? Do you think so? You might be surprised by our analysis of what is and isn't safe, according to US regulations about ionizing radiation. See what you think, and take the short quiz at this page.

An ANSI standard has been published about fetal dose calculations, in radiotherapy, nuclear medicine, diagnostic radiology, and the general workplace, with a discussion of how to interpret and communicate calculated doses to a pregnant woman and/her physician (the latter by Dr. Robert Brent, head of the Clinical and Environmental Teratology Laboratory at Jefferson Medical College and duPont Hospital for Children). This document is free to Health Physics Society Members, or at a low cost to the general public. A RADAR member contributed to this document and chaired the working group.

A lot of people out there want to scare the heck out of people with estimates of cancer risk from low dose medical procedures. Everyone knows that the benefits of the medical exams far outweigh whatever theoretical cancer risks may (or may not) exist at these low levels. Well finally, Dr. Pat Zanzonico of Memorial Sloan Kettering Cancer Center has evaluated the magnitude of the BENEFITS of a few medical procedures that involve radiation and compared them numerically to these theoretical cancer risks. This eye-opening analysis can be found here. Everyone agrees that exposures should be kept as low as reasonably achievable, and that unnecessary repeated examinations using radiation should be avoided. At the same time, though, we should appreciate these large benefit/risk ratios and not avoid necessary medical examinations.

BREAKING NEWS....RADAR researchers discover rarest substance in universe...

Click on the image to uncover its amazing identity!!!!!!

Hey we didn't even have funding for that research. But since we got that figured out, we've been pretty busy on some writing projects....

This one has problems with worked solutions for many of the chapters. You can preview the Table of Contents here. You can download the Word files for this right heeeeeeeeeeere. The problem files are available to all, but the solutions files are password protected. The password can be obtained by emailing the author. If he can tell you aren't a student doing homework, that is....

The 'Fundamentals of Nuclear Medicine Dosimetry' is like the 1988 MIRD Primer - theory of dosimetry, discussion of models, and lots of worked out examples. You can preview the Table of Contents here. The Primer was a good start, but this is like long-lasting RADAR paint that is guaranteed to transform your lackluster dosimetry results into shining, durable perfection. Beware of faux finishes by other groups which may be unreliable and may not provide adequate coverage.

Springer did a great job on these. Get yours now at Amazon by clicking either of the book cover images above.

RADAR is a working group of professionals from several countries and disciplines. We believe in facilitating the work of people like you, who need dose assessment models, methods, and results for your work. We have designed this site to be especially useful to those of you in third world or developing countries, where access to some published materials may be difficult to obtain. Our goal is to continually propose and create new and better ways to get this work done, to collect and organize such information from other sources, and to put it on this site as soon as it is available and tested, for you to use.
