You can't prove a particular individuals cancer was due to smoking or TMI.
You're making a nonsense argument.
In addition, standardized incidence ratios for the TMI population could be not be examined because the completeness of the registry with regard to individuals who may have chosen to leave the area is in question. As there is no national cancer registry, those from the cohort who may have left Pennsylvania would be lost to follow-up, resulting in incomplete ascertainment of cancers.
I don't have time to spend on this, but it's not hard to find critiques of the study:

Some recent press reports have suggested that cancer rates around Three Mile Island in the U.S. state of Pennsylvania are unchanged since the 1979 accident. Eric Epstein, chairman of Three Mile Island Alert and coordinator of the EFMR Monitoring Group, describes how this latest study - which did in fact acknowledge an increase in some types of cancer - fails to tell the full story.(576.5457) Eric Epstein - The University of Pittsburgh's most recent health study is essentially a recitation of discredited protocol and disputed data. Released on 31 October 2002, the Study actually acknowledged an increase in lymphatic and blood cancers among men. However, as in previous of University Pittsburgh Studies conducted by the same group of researchers, e.g., (Evelynn Talbott et al; 2000) (1), this survey relied on government and nuclear industry sponsored "health studies" that were completed in the early 1980s. These studies were based on inaccurate dose projections, did not factor data only available in 1985 regarding the severity and conditions of the partial-core meltdown at Three Mile Island 2 (2), and did not factor the prevailing weather conditions and wind patters in March-April 1979.
Nor did any of these studies evaluate the health impact to members of our community who defueled Three Mile Island. In fact, General Public Utilities (GPU) chose not to maintain a health or cancer registry, despite the fact that, from 1979-1989, 5,000 clean-up workers received "measurable doses" of radiation exposure (3).
Moreover, the University of Pittsburgh's Study relied heavily on the much maligned Pennsylvania Department of Health's seventeen year-old survey released in September 1985. That study's protocol was ridiculed and criticized by epidemiologists at Harvard (Dr. George Hutchison), and Penn State (Dr. Robert A Hultquist) for "diluting" increases in cancer by "expanding" the population base to include people living outside of the ten-mile study-zone (October 1985) (4).
A great deal of radiation was indeed released by the partial core melt at TMI. The President's commission estimated about 15 million curies of radioactivity were released into the atmosphere. A review of dose assessments, conducted by Dr. Jan Beyea, (National Audubon Society; 1984) (5) estimated that from 276 to 63,000 person-rem were received by the general population within 50 miles of TMI. More recently, David Lochbaum of the Union of Concerned Scientists, estimated between 40 million curies and 100 million curies escaped during the accident.
For 11 days, in June-July, 1980, Metropolitan Edison (Met Ed) illegally vented 43,000 curies of radioactive Krypton-85 (beta and gamma; 10 year half life) and other radioactive gases into the environment without having scrubbers in place (6).
And by 1993, TMI-2 evaporated 2.3 million gallons (8,700 cubic meters) of accident generated radioactive water, including tritium (a radioactive form of hydrogen), into the atmosphere despite legal objections from community-based organizations (7).
The plant's owners, co-defendants and insurers have paid over US$80 million in health, economic and evacuation claims, including a US$1.1 million settlement for a baby born with Down's Syndrome (8). In June 2000, the United States Supreme Court remanded 1,990 unsettled health suits from the TMI-accident back to Federal Court (GPU v. Abrams; Dolan v. GPU) (9).
In August 1996, a study by the University of North Carolina-Chapel Hill, authored by Dr. Steven Wing, reviewed the Susser-Hatch study (Columbia University; 1991). Dr. Wing reported that "...there were reports of erythema, hair loss, vomiting, and pet death near TMI at the time of the accident...Accident doses were positively associated with cancer incidence. Associations were largest for leukemia, intermediate for lung cancer, and smallest for all cancers combined...Inhaled radionuclide contamination could differentially impact lung cancers, which show a clear dose-related increase." (10)
Today, TMI-2 remains a high level radioactive waste in the middle of the Susquehanna River. There was no decommissioning fund established for TMI at the time of the accident. The site of the nation's worst commercial nuclear accident has not been decontaminated or decommissioned. There has not been a human entry in the basement of the reactor building since March 1979...

2. On 6 November 1984, research conducted by the Department of Energy on reactor damage during the accident, indicates temperatures may have reached in excess of 4,800 degrees Fahrenheit (2480 degrees Celsius). In October 1985, removal of damaged fuel from TMI-2 began.
3. On 11 April 1984, William Pennsyl settled out-of-court two days before an administrative law judge was scheduled to hear his case relating to GPU¹s refusal to allow Pennsyl to wear a respirator during cleanup activities. By 1986, TMI-2 defueling work force peaks at 2,000, but by 1989, after ten years of defueling activities, 5,000 TMI workers have received "measurable doses" of radiation exposure.

6. In November 1980, the United States Court of Appeals for the District of Columbia ruled that the krypton venting (June-July 1980) was illegal.
7. In 1980, the Susquehanna Valley Alliance, based in Lancaster, successfully prevented GPU/Met Ed from dumping 700,000 gallons (2,700 cubic meters) of radioactive water into the Susquehanna River. Ten years later, in December 1990, despite legal objections by TMI-Alert and the Susquehanna Valley Alliance, GPU began evaporating 2.3 million gallons (8,700 cubic meters) of accident-generated radioactive water (AGW). By August 1993, evaporation of 2.3 million gallons of AGW was completed over six months behind schedule. The evaporator was disassembled and removed from the site. And on 28 October 1993, according to the Pennsylvania Department of Environmental Resources, the total activity during evaporation was 658 curies of tritium.
8. By 1985, TMI had paid at least US$14 million for out-of-court settlements of personal injury lawsuits. The largest settlement was for a child born with Down's Syndrome. Most of the cases were sealed, and only those cases involving minors are published as prescribed by the rules and regulations of Pennsylvania's Orphan's Court.
9. On 12 June 2000, the United States Supreme Court, without comment, rejected an appeal by GPU to throw out 1,990 health suits. On 2 May 2001, the Third Circuit Court ruled that "new theories" to support medical claims against Three Mile Island will not be allowed.
10. New Study Shows Higher Cancer Rate near Three Mile Island Nuclear Power Reactor Meltdown. Researchers at University of North Carolina at Chapel Hill have published, in the journal Environmental Health Perspectives (24 February 1997), a reevaluation of the health effects near Three Mile Island. They have found chromosomal damage and higher cancer rates than previously reported, suggesting radiation levels were higher than official estimates. Copies of the study may be requested at: +1 919 541 3345.
11. In December 1993, GPU placed TMI-2 in Post-Defueling Monitored Storage. On 17 October 2001, due to a "credible threat" against Three Mile Island, the Harrisburg and Lancaster airports were closed for four hours, air travel was restricted in a 20-mile radius, and fighter jets were scrambled around TMI.
