I'm only hanging on to watch you go down

I'm not really clear how this happened, but I'm glad it didn't happen to my summer student.

The guy working in the lab next door? Got ~9000cpm of radioactive ATP on his trousers. Right on the crotch.

What was he doing, humping the lab bench?

that is just mind-boggling.

Better a man than a woman? Or is my high school biology failing me again?

OMG. That's terrible and amusing at the same time... only because just how *DID* he get it there??

cpm?

Futurama reference:
Bender aims F-ray at Fry's crotch.
Fry: "Ow, my sperm!"
Bender: "Let's try that again."

Fry: "Hmm, didn't hurt that time."

Oh dear. That's not good. *crings*

The thing is, I can't say I'm surprised. Every summer one of the visiting students does something that makes us shake our heads and wonder how on earth it happened. At least it was only P-32.

[asimplechord.livejournal.com]

Yeah, better for a man since sperm regenerate. I don't think that amount and form of radioactivity (P-32, a moderate-energy beta emitter) would do series damage as long as it's external and not near the corneas. But it caused a stir among the lab safety dept, and the lab coat and trousers had to be confiscated.

cpm = counts per minute = disintegrations per minute = the units of radioactivity scintillation counters measure

The standard unit for purchasing radioactivity is a Curie, and 1 Ci undergoes 2.22x10¹² disintegrations per minute.



I need to watch Futurama. I think I'd probably like it. :)

Apparently he likes to lean against the edge of the lab bench. And he didn't realize that the puddle of wetness might be something other than pure water. When I told MrIris about it, he thought it wasn't unusual -- he used to get chemicals on his pants all the time from leaning against the bench. Must be a guy thing.

[asimplechord.livejournal.com]

No, not good.

He might get the trousers back in three months. As it was, they had to find something else for him to wear home.

Bad mental image! Down boy!

Seriously, if one of the profs didn't have his gym shorts there, the student would have either had to go home naked or get someone to buy him a pair of scrubs from the med school bookstore.

Is he cute at least? Gives me interesting thoughts for our scientist:)

[scotrid.livejournal.com]

Now, I was thinking curies per minute or counts per minute, but the context seemed like it should be a volume of liquid.

Is my dictionary wrong? It says a Ci is 3.7x10^10 disintegrations/min.

[asimplechord.livejournal.com]

Hmm, we use the 2.22e12 for cpm to curie calculations. I'm not sure where the 3.7e10 fits in. I've gotten lazy though - I've been doing it so long I just stick the numbers in a calculator without thinking about the unit conversions. But you know, I think we assume that cpm to dpm counting is efficient, and that is not the case for all nuclides. In some cases, cpm=/=dpm, it's cpm=N*dpm, where N=some coefficient to describe efficiency of the counter. That might be where the 3.7e10 comes in.

We usually use a set amount of curies per fixed volume in a reaction tube, then calculate from that how many nanomoles are consumed in a catalytic reaction.

He's tall, with dark hair and dark skin. Not bad looking. But still in that awkward, doesn't know what to do with limbs that recently grew stage.

eeeek omg! I hope everything is ok!
