Kodak Aero Ektar 178mm f2.5 Lens - Radioactive (Thorium Glass Elements)

[@kurtstory9466]

I’m always impressed when people methodically take dosage rates at various distances-that’s how to do it right. You got the complete package, with what looks to be an original wartime box. You can determine the production date of the lens using this code: where C=1, A=2, M=3, E=4, Y=0 etc. EA= 1942. EE = 1944 etc.

My year is ER .What number does R equate to?

[@breadgitarian]

@@daveandrews6384 ER means is was made in 1945. In the early 1940s Kodak made up the word "Camerosity" with 10 non-repeating letters so they could include the last 2 digits of the production year at the start of a lens serial number. Kodak parts in the UK used the word "Cumberland." C A M E R O S I T Y 1 2 3 4 5 6 7 8 9 0 C U M B E R L A N D

I checked all sorts of things while I had the meters here and the Clansman was one; nothing from the Clansman meter at all, just normal background. Either it has "run out" or the meter has been changed for a new, non-radioactive one?

[@f109ged]

I'm wondering if you'd get a reading off your Clansman 320 meter?

Hoping you will reply as it is an older video. Nice one! Do/did you leave the Ektar on your Kodak or did you remove it everytime you were done shooting?

Be careful when taking this lens to some countries. I went to Russia in 2022 to photograph hot models, I got this lens confiscated at Moscow airport. Freaking bastards. I paid 3000$ with adapter for Pentax 67. Russians guys came with dogs and special forces to block me and started to measure. Obviously their method of measuring were false they just put so close to rear element to it was screaming radiation but once they were like 15cm it was normal , they didn’t respected measuring protocol and when I requested the manual protocol they said it’s too secret. Haha top secret my ass. Received answer from them , because they send the lens to the lab. Answer « must be buried immediately, extremely dangerous for public health » . Yeah my ass , sent to Ukrainian war that’s what they meant. But I agree it’s a highly radioactive lens , be careful
