I was thinking of mentioning Hadoop/MapReduce or Cassandra, but these technologies are a big change from Radu’s current implementation, and the learning curve is steep.
Very cool technology though. At my work I design/maintain a 500 gigabyte SQL Server data warehouse with almost 400 tables in a denormalised star schema – have been trying to get my bosses to look at hadoop and MapReduce, but it’s ‘new’ tech and therefore complex and scary 🙂
Love the example screenshots! Here’s a few things I’ve been thinking of – I’m not really considering feasibility right now – just throwing ideas out there into the pot.
- Ability to search for units by ID, geographic location, etc – and to filter/order a list by CPM/dose rate/uSv/h, etc
- I’d like the permissions of the app to be constrained to only those that are really necessary. The number of apps now that ask for full access to your camera, contacts, microphone, etc is shocking. Hopefully we can design it in such a way to be minimally intrusive.
- IFTTT (https://play.google.com/store/apps/details?id=com.ifttt.ifttt&hl=en) integration – the ability to chain alerts into other Channels might be useful. For example; if my monitor registers CPM above a pre-defined threshold, email Radhoo and say “goodbye, nice knowing you”, etc.
- Ability to set a favourite station, or stations, which will appear in your ‘dashboard’ or stats, without having to go into a list or map view to find them. For example, I could favourite or ‘star’ the three Orlando units – and would see their information together in one place thereafter, without searching for those units.
Here’s a list of civil Nuclear power stations worldwide, from IAEA data, but not sure how recently it’s been updated.

And here’s a list of civil facilities in the USA licenced to handle radioactive material – Uranium mine/mills, reclamation, etc;
I think that’s a great idea. There must be lists of locations somewhere – the civil ones anyway. The military ones might be harder to plot – but we could plot the main ones manually.
In the UK for instance, all nuclear weapons are stored in Scotland, just outside Glasgow, the largest city (as far away from London as possible!) at a place called RNAD Coulport (Royal Naval Armament Depot Coulport).
Wikipedia has a huge list of all the civil ones from International Atomic Agency data, but they don’t have coordinates for plotting a map. Google time!
There are some pretty good mapping products/overlays for Google maps that allow categories of locations, searching by location, filtering, etc.
Hi guys,
Yes, I agree with you both – the decentralisation of the single server model shshould be in our top 10 priorities. To defend against everything from hardware failure to malicious attacks.
How about if duplicate servers were hosted by trusted volunteers – the units could send data to the primary server until it becomes unreachable, then would send to a secondary, then the tertiary server if the secondary fails, etc. We’d have to write some form of data replication (as close to real-time as possible) to keep all the servers in sync with each other – so when primary comes back online it receives the data collected by the secondary, etc. There are definitely better solutions, but I do it this way for a cluster of servers at my work, and it definitely works.
