Re[2]: Beta Skin Dose question

     I believe the actual experiments were actually performed at Battelle.
     
     
     Try these documents
     
     EPRI TR-100048
     PROJECT 3099-2
     April 1992
     
     "Threshold Levels for Nonstochastic Skin Effects from Low Energy 
     Discrete Radioactive Particles.
     
     
     
     EPRI TR-102658
     PROJECT 3099-09
     October 1993
     
     "Nonstochastic Skin Effects from Discrete Radioactive Particles 
     Emitting High Energy Spectra Beta Rays"
     
     
     
     I have a draft of the following document that was also sponsored by 
     EPRI.
     
     "Skin Injuries from Discrete Radioactive Particles and the 
     Implications for Nuclear Power Plant Radiological Control Practices"
     
     This was a summary of EPRI experiments conducted at Battelle Pacific 
     Northwest Labs.
     
     
     There was even a draft industry proposal that may have been issued 
     throuth the NEI to set the limit for hot particle to 200 micro-Ci that 
     seem to come out after the final review by the persons in Texas of the 
     EPRI experiments.  I have heard nothing since.
     
     
     As far as pigs go, they are a good test subject with skin that is not 
     too dissimilar from our own.  It appears that the pigs had 50 or more 
     sources on them at one time; most likely to get good statistics.  The 
     pigs look a little like Bonnie and Clyde after they met up with the 
     law...  Of course, a few small piddly scars never hurt anyone...
     
     
     
     See if you can chase down Jim Durham somehow.  I believe he may have 
     been involved in some of the experiments and he is also responsible 
     for writing the new revision of Varskin.  He is an excellent source of 
     knowledge.  He is last known to still be working in the Battelle area, 
     but not directly in skin dose research.
     
     I believe the HPS summer school may cover some skin-dose related 
     topics.
     
     
     
     Good luck

     NCRP 106 will answer all of your questions in sufficient detail or 
     refer you to more than you would probably like to read on the subject 
     in a year.
     
     Good luck.

     I am an Instructor at a Nuclear Power Plant and I've heard rumors of a 
     study done at Texas Tech? in which high activity particles were placed 
     on pigs in order to determine the total acute dose at which the 
     earliest non-stochastic effect could be detected. Is anyone familiar 
     with this study, and can you tell me the effect and doses involved? 
     Also as an aside I'd like to know the reasoning behind the use of 
     pigs.
     
     Thank you.
