Re: NCRP 136 and 137 now available

["Jerry Cohen" <jjcohen@PRODIGY.NET>]

    I have reviewed and commented on NCRP-136. One aspect of this report

that I did not comment on has me puzzled and perhaps someone else who has

reviewed the report can enlighten me.

    Most of the material covered in Chapters 3 to 9 seemed to be irrelavent

to the overall subject and I really could not understand how the information

discussed in the body of the report tracked to its conclusions. For example,

how does the discussion of DNA repair, oncogenic transformation, etc. affect

the question of whether LNT is a valid concept and/or reasonable basis for

low-dose radiation exposure standards????

Evaluation of the

Linear-Nonthreshold Dose-Response

Model for Ionizing Radiation

NCRP Report No. 136 on Evaluation of the Linear-Nonthreshold Dose-

Response Model for Ionizing Radiation is 263 pages long with 12 sections

and references. It begins with 1. Executive Summary followed by 2.

Introduction, 3. a Biophysical section, and 4. Deoxyribonucleic Acid Repair

and Processing after Low Doses and Low-Dose Rates of Ionizing Radiation.

These are followed by 5. a section on Mutagenesis, 6. a section on

Chromosome Aberrations Induced by Low Doses and Low-Dose Rates of

Ionizing Radiation, 7. Oncogenic Transformation In Vitro and Genomic

Instability, 8. Carcinogenic Effects in Laboratory Animals, 9. Carcinogenic

Effects in Human Populations"Epidemiological Data, 10. Adaptive

Responses, 11. Research Needs, and concluding with 12. Discussion and

Conclusions.
