Gamma dose rate (D=AE/6r2) - or is it? A widget to calculate the validity of this formula.
Published: Apr 02, 2024
Source: Design & implementation by Dr Chris Robbins (Grallator) / Facilitated by Ionactive radiation protection resource
Read moreThis resource uses a radiation protection widget to explore the validity of a popular gamma dose rate formula of the form:
\[ \begin{align} D_{\mu Sv hr^{-1}} &= \frac{AE}{6 r^2 } \end{align} \]
where D is dose rate in µSv/h, A is activity in (MBq), E is gamma ray energy in MeV, and r is the distance in m.

Shielding gamma rays with thick water shielding - what if you fall in?
Published: Mar 31, 2024

Read moreLarge volumes of water (in pools / ponds) are often used for radiation shielding, particularly for spent nuclear fuel and high activity Co-60 sources in industrial irradiation facilities. The water provides shielding and cooling whilst allowing remote movement of highly radioactive items where operators stand safely outside the pool. Imagine falling in - how would you fair? Very well if you can swim as illustrated in this radiation protection widget.

Read moreUse this interactive ALARP / ALARA calculator widget to investigate the effect of time, distance and shielding on radiation dose rate and accumulated exposure. A great radiation protection training / educational aid - learn the concepts first, then investigate them interactively! Explore how best to optimise exposure by using a combination of all three protection methods.

X-ray Tube Dose Rate Calculator Widget
Published: Mar 28, 2024
Source: Design & implementation by Dr Chris Robbins (Grallator) / Facilitated by Ionactive radiation protection resource
Read moreA radiation protection widget which calculates dose rates from an x-ray tube for a given kV, mA and filter (Al). This resource is strictly for training / educational use - that said, as a ballpark resource it gets pretty close to what you might expect from a typical x-ray tube.
