             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

                 NINE MONTHS ENDED SEPTEMBER 30, 1998 AND 1997

         In the opinion of the Company, the accompanying unaudited consolidated
financial statements contain all adjustments (consisting of only normal
recurring accruals) necessary to present fairly the financial position as of
September 30,1998, and December 31, 1997, the results of operations for the
three and nine months ended September 30,1998 and 1997 and cash flows for the
nine months ended September 30,1998 and 1997. The consolidated financial
statements include the accounts of the Company and its subsidiary. All
significant intercompany transactions and balances have been eliminated in
consolidation.


(1)  MARKETABLE SECURITIES

                  Upon adoption of FASB No. 115, management has determined that
the company's portfolio is best characterized as "Available-For-Sale". This has
resulted in the balance sheet carrying value of the company's marketable
securities investments, as of September 30, 1998 and December 31, 1997 being
increased approximately 79.17 % and 70.90 % respectively over its historical
cost. A corresponding increase in shareholders' equity has been effectuated. In
accordance with the provisions of FASB No. 115, the adjustment in shareholders'
equity to reflect the company's unrealized gains has been made net of the tax
effect had these gains been realized.
         The following tables summarize the company's investments as of:

Part II OTHER INFORMATION
-------------------------

Item 1.
-------
Legal Proceedings
-----------------

         As reported in previous filings, Daxor Corporation, (through its
separately licensed divisions), has been involved in various proceedings with
the New York State Department of Health relating to its licenses to operate
clinical laboratories, its blood bank and semen bank. During the past 15 months
the Company has engaged in negotiations to end these legal proceedings and to
re-open Daxor's Idant semen and blood banking facilities, which have operated
in a limited capacity and were unable to take new clients. An agreement was
signed on November 3, 1998 to end all current litigation between Daxor
Corporation and the New York State Department of Health. The agreement calls
for the establishment of a separate wholly-owned subsidiary, Scientific Medical
Systems, with a separate Board of Directors, for the operation of Daxor's New
York semen bank and long term frozen storage blood bank. The Board of Directors
of the subsidiary were appointed by Daxor's Board of Directors and approved by
the New York State Department of Health. New Directors were appointed by the
subsidiary Board to direct the semen bank and blood bank. The subsidiary will
function only within New York State. Daxor's Idant Laboratories semen bank is
the only semen bank in the State of New York accredited by the American
Association of Tissue Banks (AATB). The agreement also includes the dropping of
anti-trust litigation against the New York Blood Center, which was included as
part of the legal actions against the New York State Department of Health.
Daxor retains the right to file a separate suit against the New York Blood
Center. The Company also expects to enter an agreement to end its lawsuit
against the K-III Corporation.



                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                 RESULTS OF OPERATIONS AND FINANCIAL CONDITION
ITEM 2.
-------
RESULTS OF OPERATIONS
---------------------

Nine months ended September 30, 1998 as compared with nine months ended
-----------------------------------------------------------------------
September 30, 1997.
-------------------

         For the nine months ended September 30, 1998, total revenues were
$2,088,320 down from $2,624,810 in 1997. Operating revenues were $259,303 in
1998 down from $420,897 in 1997. Dividend income was $1,475,648 with a net
interest expense of $447,464, as compared to dividend income of $1,611,393 with
a net interest expense of $114,375 in 1997. In 1998, the Company had a net loss
of $167,018 before income taxes versus a gain of $852,090 before income taxes
in 1997. Operating revenues have been sharply decreased because of legal
actions against Idant Laboratory's semen and blood banking facilities here in
New York State. Some of these actions date back almost ten years. During the
past three years the Company's revenues from laboratory and blood banking
operations have been severely reduced because of these actions. The Company
filed various suits in both State and Federal court against Department of
Health officials. On November 3, 1998 Daxor and the Department of Health signed
an agreement which will lead to the re-opening of the Daxor facilities under a
separate subsidiary. The Company anticipates that this will increase revenue
from these sources. The Company has not yet received any income from the Blood
Volume Analyzer, which is in the process of being introduced to hospitals. The
Company currently has Letters of Intent from ten major teaching hospitals to
test the Blood Volume Analyzer. The Company expects that as the Blood Volume
Analyzer sales increase, the relative significance from semen banking services
will diminish. The company may expand its blood banking operations into states
outside of New York.

LIQUIDITY AND CAPITAL RESOURCES
-------------------------------

                  At September 30, 1998 the Company had total assets of
$43,179,990 and total liabilities of $8,054,790 with shareholders' equity of
$35,125,200. The Company has a net pre-taxed gain of $18,639,713 and
$12,302,210 of net after tax unrealized capital losses on available-for-sale
securities in its portfolio. This amount is included in the calculation of
Total Shareholders' Equity. The Company's stock portfolio had a market value of
$42,184,210 with short-term loans of $1,659,481 with 4,760,709 shares
outstanding.

                  The Company acquired the assets of Wellport, Inc. of
Rochester, NY. Wellport has been the manufacturer which has fabricated the
patented Blood Volume Analyzer injection syringe. Mr. Daniel Wellington,
President of Wellport, was appointed a Vice-President of Daxor Corporation. The
Company is currently in negotiation with a radio-pharmaceutical company to
dispense the kit.

                  The Company has adequate resources for the marketing of its
Blood Volume Analyzer and the liquid capital to sustain its blood bank. If the
Company were to expand its blood banking operations on a full scale,
nation-wide basis, it would require additional capital. The Company's financial
reserves have played an essential role in sustaining the company during its
legal battles to provide frozen blood banking services to the public. The
Company has sustained a large loss of revenues and profits as a result of its
conflicts with the New York State Department of Health. The Company's immediate
main focus will be on developing and marketing the Blood Volume Analyzer. The
Company is considering expanding its blood banking operations outside of New
York State.

                  The Company did not file any reports on form 8-K during the
first nine months of 1998.

The Company has initiated a contract for a new computer system to be installed
in the next 90 days to avoid any year 2000 computer problems.
