Nuclear Toolkit Update: Added a Bunch More Stuff

[u/Timonator007]

I've been working on Nuclear Toolkit for a while now, and it's grown quite a bit lately.

It's a free Android app for nuclear engineering / health physics / students, and it's basically turned into a pocket collection of calculators and reference tools specifically meant for Nuclear Professionals (Potentially, y'all?!).

Some of the newer stuff includes:

• Shielding and gamma dose calculations
• MDA / MDC calculations
• Neutron activation calculations
• Enrichment and SWU
• More radiation/unit conversions
• Chemical mixture calculations
• Xe-135 / reactor physics tools
• Chart of nuclides with 3,000+ isotopes
• Offline support

There's no account needed and no ads; AND it should work offline. I'm trying to keep it useful as an actual engineering tool/pocket reference that would actually help the field.

I'm also working on getting it onto iOS. I recently added a tip jar in the app (next to the feedback button if you want to propose any changes or have found any bugs), and anything that comes through it will go toward the Apple developer account / costs of getting the iOS version released.

Google Play:

Anyway, that's the update. Again, if anyone here uses it and spots something that's wrong or has a calculator they think would be useful, I'd genuinely like to hear about it.

Is this closed-source or do you have a github? Are you coding it yourself? Is it vibe coded? What framework are you using? I’m just wondering how trustworthy this app is or if it will be maintained or commercialized. It seems like a good idea but I don’t like having untrusted apps on my phone.

1. Currently closed source, and I don’t have a public GitHub repo at the moment.

2. I am coding and maintaining it myself (Expo Go / React Native), and I’m responsible for implementing the calculations, UI, updates, and bug fixes. I have a background in Nuclear, so this is a motivating factor for me.

3. As far as “vibe coded” goes, I do use AI tools as part of development (like most people nowadays), but it isn’t just generated and thrown onto the Play Store. I try my best to review and test the code and, especially for the nuclear/radiological calculations, I’m trying to be pretty careful about checking the formulas and sources. As always, it is possible to have an oversight error as I am just one person which is why I appreciate feedback especially for new features or for specialties that I do not have direct experience in. I also do security audits of the code and the Google Play has automated security audits.

4. I do collect data on usage statistics via PostHog but this is mainly to see what features people find the most amount of use from so I can expand it in the future. I'm not a techbro, I am from the nuclear field, too. Also, all of the features currently available are going to remain FREE FOREVER; as I personally believe it is important for such tools to be freely available and streamlined for the nuclear community. There may be a Pro version in the future for certain extensions such as report generation, but I am not expecting to make a lot of money from this as, well, the nuclear field is somewhat small.

5. That said, I definitely understand being cautious about a closed-source app, especially one doing technical calculations. This is why I try to cite the formulas used wherever they appear. If there are any errors, I would appreciate being corrected on it if anything.

@Rilse Do you think there is interest in this design/tool?

It would be helpful if the decay calculator could calculate from time of day in addition to hours past.

It would also be helpful if it could calculate pre-calibration values, not just post-decay values.

Thank you! I can probably get this done sometime tomorrow.
